Book 10 COVER REVEAL!

Posted on 82 Comments

Coming to stores SEPTEMBER 29, 2026: SERIOUSLY, CELIA?

Announcing the next book in the Emmie & Friends series! Yes, you’re not imagining things. This edition will be out later in the year than usual (I know, boo!). After a decade, I’m giving myself a little break to work on other projects. But don’t worry, the E&F series is still going. AND this time, it’s starring the two most requested characters of 2025!

SERIOUSLY, CELIA?* is the tenth book in the New York Times bestselling Emmie & Friends series. It’s all about that Queen Mean of Lakefront Middle School, Celia, and her sometimes-reluctant sidekick, Grace. Yes, we finally get to see what makes them tick!

Synopsis:

Summer break. Second chances. MIDDLE SCHOOL.

Celia is bored. It’s the summer before eighth grade and hanging out with Grace and Lindsay is getting old. So she makes a plan to get her former besties, Jaime and Maya, back. And Celia knows just the person to help reunite them…

Grace is anxious. She loves Cee, but lately Grace is starting to feel more like Cee’s lackey than her friend. Still, without Cee’s popularity to hang on to, Grace would be a nobody—and there’s nothing worse than that.

Celia is determined to get their friend group back together by any means necessary, but Grace isn’t sure she wants to be friends with Celia anymore…even though that means the unthinkable: starting the school year (gasp) completely alone.

For ages 8-12.

*note: all these books can be read in order as written or as stand-alones

  2. Hello!
    I’m so happy that this series is continuing!! I have always loved the Emmie and Friends series, (the first book I read was Just Jaime, one of my favourites!) so I’m so happy to see more into Celia and Grace’s lives and personalities! I will definitely be reading “Seriously, Cee?” when it comes out. My favourite books in the series so far are Just Jaime, Becoming Brianna, and Positively Izzy!

  5. I actually have a lot to say…
    You didn’t have a series in mind when you first wrote Invisible Emmie, did you?
    The way the time jumps around (later books sometimes being set before earlier ones) can be a little confusing, honestly. And with all the books so far set in that seventh grade year, it’s getting pretty crowded. I saw that Seriously, Celia? is set in the summer after seventh grade, and I guess it was inevitable that you’d have to move the time forward.
    The funny little images representing people’s thoughts (e.g. the “Bad Speling” monster)? <3
    I always thought the series felt incomplete without focusing on Joe, so when he was finally focused on in Entirely Emmie (what happened to the italics?), along with Emmie being focused on for the third time, it seemed like a series finale somehow. But without Celia being focused on, it still felt incomplete. Glad to see we’re finally getting her side of things, because that’s kind of the whole point of the series: everyone has their side of things.
    It feels like you’re running out of characters to potentially focus on. The only ones I can think of are Dev and maybe Juan.
    Although Surprisingly Sarah had two different timelines, in Entirely Emmie it was mentioned that Sarah brought Leo to the spring dance, implying that the “she lost her nerve” timeline is the one that actually fits with the rest of the series.
    The exact time setting is ambiguous, but I think I’ve figured it out. In Positively Izzy, Izzy’s chapters are set in the year she turned thirteen, and she turns forty in the present time; that’s a twenty-seven year gap. The test Izzy forgot about says “due 3/13”, which was a Friday, the day of the talent show. March 13 was on a Friday in 1992 and 1998. Twenty-seven years later is 2019 and 2025. A flashback at the beginning of Always Anthony shows Anthony’s mom recalling a day in late 2019, which implies the series is set in 2024-2025, on a non-Covid timeline.

    • Hi, Jose. Wow, you’ve noticed so much. Bravo! I think you’ve paid attention more than I have 🙂

      To answer your question, I indeed did not have a series in mind when I wrote INVISIBLE EMMIE. So glad it worked out the way it did because I enjoy writing for these characters. I may not get to ALL of them, but I hope to cover the majority.

      You have a sharp eye for the timeline dates and details. To be honest, I’ve tried to keep on top of it, but I’m sure there are little errors (you may like my blog post, titled “Oops.”). It does get hard keeping track of it all!

      I hope you continue to enjoy the series and find all the fun crossover details.

    • Okay this is awkward. There doesn’t seem to be any way for me to adjust or remove comments I’ve left here if I no longer feel like I want my thoughts pasted in this open space, just set in stone like this when real life is never set in stone like that.

      Reply

      • If you let me know which specific comments you’d like removed, I’d be happy to do it. I know it’s hard to leave something in the open like that. (Feel free to send me an email if you’re more comfortable.)

  6. Hi Terri!
    I love all your books and I’ve emailed you before! So excited for Seriously Celia. I do have a few questions. First of all, how many Emmie and Friends books do you think you’ll write? Also, will there be any new characters in Seriously Celia? One more question is does Leo like Sarah and does Dev like Bri? Lastly, why are Emmie’s parents never shown?
    Thank you so much! I really love your books 🙂
    Kind Regards,
    Olivia

    • Hi Olivia! To answer your questions:
      1. So far there are eleven planned books.
      2. You’ll see a few new characters, all family members of Cee and Grace.
      3. That all remains to be seen! 🙂 (but if you think there may be sparks between the characters, there probably are)
      4. In the first book, Invisible Emmie, I wanted to focus just on Emmie. But I decided to open it up more to families as I wrote the other books (since many of the plots involved family interactions). I just never found it necessary to revisit Emmie’s parents that way. But who knows in the future!

  7. Ooo, finally! Always been curious about Cee, but I assumed she would never get a book! I kinda thought she’d just be an antagonist. I’m so excited! I got into this series when I was in the target demographic and even though I’ve kinda aged out of it I still read these books with joy!

    Question, will we get to see a young Cee and her old best friend? It was mentioned in Just Jaime that her old best friend went to private school, and I’m curious if that relationship shaped her in some way?

    I’ll stop talking now, but yay! Have a great break, Terri!

  8. Hi!
    I love your books, but I just want to know where Katie goes after Invisible Emmie. Also, I was wondering what characters you will add after Seriously, Celia?. The only characters I can think of is Lindsay and Dev, and maybe Trina.

    Thanks!

  9. Hi Terri! I am sooooo excited to read Seriously, Celia? I have always found Celia mean and I’m curious to why she is, so I’m so happy we’re getting her side of a story! I have read all of your Invisible Emmie books and my favourites are probably Entirely Emmie, and Just Jaime! I have a question, it seems like Izzy is the same age as Brianna and is there, at the talent show and maybe even getting Taystees at the same time as Brianna is in Positively Izzy. But Izzy is actually Brianna’s mom. I don’t really understand that. Thanks!

    • So glad you like to read the books and I hope you enjoy CELIA!
      Here is the answer to your question: (((Spoiler alert for those who haven’t read POSITIVELY IZZY!))) Izzy’s chapters actually take place in the past. The timeline just seems to echo the present day (when Brianna is in the talent show and Izzy is the mom/teacher). If you go back and read Izzy’s chapters, you may see some clues and notice that young Izzy and Bri are never really in the same room.

  11. Hi!! I’m so excited on this book and will be counting days!! I’m actually so glad you found out the little ( and big ) mistakes you made in the old books because I was very confused. I’m glad that we’ve also started going more further near 8th grade in the books gradually, since I’ve been making tons of theories of the summer before 8th grade but now, I’ll be making even more! Here’s one of them: Cee will either use Grace as a guilt tripper for Jaimie and Maya, and both will either have different opinions, OR Celia uses Lindsay to pressure them both into forgiving her, and using Grace as a manipulator. These are my top two theories and I hope I did’nt spoil nothing! Love your books, its my fav series EVER!!!!

  12. YESSS I’ve always wanted a book from Celia and Grace’s (especially Grace’s) POV. Can’t wait to read this!

    Reply

  13. Theory: Celia is using grace by getting gossip ( Reference to in Just Jaime when she said that Grace gets all the gossip because no one notices her) about the friend group that Jaime and Maya are in and use it against the group to break them apart. Making Jaime and Maya join back with Celia.

    Reply

  14. OMG!! A new book in the E & F series l? Count me in! This one sounds great! My theories for Celia is that no one liked her at her old school or something like that. Also while reading your description of the book I realized that All the giggling and gossiping of Grace is probably because she wants to make her friends happy and like her. Probably something to do with her past. Sad people can tend to feel like they need to make everyone else happy because they know how much it sucks to be sad. Also I’m excited to hear about the parents, especially Cee’s. Anyway I can’t wait to read it!!

  15. AHHHHHH Im sooo excited for this book!! I literally made a whole slideshow presentation on why they deserved a book and I’m sooo excited to hear about Celia’s home life as well in the story because in entirely emmie, Trina knows about Celia’s tough home situation. And I’m also hoping that Maya and Jaime will give grace second chance!! I’m so excited. And can we plssssss make a ship nam for dev and Brianna plssss

        • So glad you’re enjoying the books! Definitely don’t have to read in order.
          No favorite characters; they’re my children and I can’t pick favorites. 🙂 (although Joe often needs a time-out)

  17. hii terri, im chloe and 15 and i still absolutely adoreeeee your booksssss!!! fan since 2020 🥹❤️‍🩹 just wanted to let u know that i am so so super excited for seriously celia omggggg!!!! ive always wondered about celia and what goes on in her mind to act this way and peform certain behaviours, especially what she did to jaime and maya, and why she’s this controlling, mean, judgy and honestly pretty self-absorbed person to begin with, and i cannot wait for this book to release so that we get to find out more about her!! and especially with grace too, i always sympathised/resonated with grace even though i was never put in her position myself because i knew what it felt like to give up everything and anything for someone else to keep them as your friend or your status, even if it meant literally worshipping them and giving up your entire personality and worth for them too, and i honestly was so curious about grace too and wondered what it must be like from her perspective, practically kissing cee’s butt all the time and if it ever gets tiring for her, if she ever wakes up or is actually aware of how celia is controlling her but yet still does it? i hope that makes sense hahaa, im so hyped for this next book in the series and i was just wondering if cee gets a character redemption arc in this book? or grace, even though she never really had one to begin with? thanks so muchhhh aaahhh 🥹

    • Hi!
      1. Sounds like Truly Tyler is being borrowed by someone else right now. But next time you’re there in person, you can ask the librarian just to make sure.
      2. So far there are nine books out. The tenth, SERIOUSLY CELIA?, comes out this Sept 29, and there will be an eleventh book coming out in spring of 2028. After that, I’m not sure!
      3. Yes, Grace will be in the next book, SERIOUSLY CELIA?.

      • I am so exited to learn what goes on in Celias head. To be honest I am a newbie cause I just started reading these books. I got introuduced by remarkable ruby and then I figured out there was a whole series.
        (P.S I just read it again and the 1st time i read it I totally missed they were sisters, LOVED that plot twist) YOU ARE SUCH A GOOD WRITER!

  29. I’m so excited for CELIA! This is the book I have been waiting for in the series(but all the other ones are perfect too)!!! As a kid in sixth grade, I can’t say I have met anyone like Cee, but the experiences of middle school for all the characters is similer to mine(good and bad)! Last year I basically binged your books for like the 100th time and started to wonder whether my Vermont middle school was going to be anything like Lakefront haha! I’ll have your new book the second it comes out hopefully!

  31. HI TERRI!!!
    I AM ACTUALLY SCREAMING ABOUT SERIOUSLY, CELIA? 😭😭 I’ve been WAITING for a Celia book for sooo long and I cannot believe it’s REAL!!! Like out of all the characters… CELIA??? THE DRAMA??? THE CHAOS??? I’m not ready 😭✨
    I’m so excited (and honestly terrified lol) to finally see things from her perspective because she’s been such a huge part of the series for so long. I keep wondering—is she going to have a redemption arc?? Am I about to feel BAD for her??? I don’t even know what to expect but I KNOW it’s going to be amazing.
    Also the fact that it involves Grace and her old friend group?? I can already tell this is going to be one of the most dramatic books yet and I am HERE FOR IT 🔥
    Thank you so much for this series—it literally means so much to me, and I seriously cannot wait to read this book!!!
