Apprentice Alliance
Sorrel is the unruly daughter of the heads of the Mage Council, protectors of the secret realm of the Mage Pocket, where libraries float through the sky, cats turn invisible, and sunlight is magic.
Theo is the reluctant apprentice of the Dark Mage, the terror of the Mage Pocket, waiting in the shadows for her chance to act.
When her parents die in a house fire, Sorrel refuses to believe it’s an accident. Theo knows it’s not, because he saw his mentor do it. He helped his mentor do it. He’s still haunted by the smell of smoke.
Sorrel is bent on finding answers, but that will require learning some complex magic. Theo is trying to break his magical apprenticeship contract, but that will require a lot of research.
Together, they form an unlikely alliance—Theo will teach Sorrel to Cast, Sorrel will help him research. But both are keeping secrets, and neither one knows the other’s true identity. As their friendship grows, so do the consequences of discovering the truth.

4 stars! Millie has quickly become one of my recent favorite middle grade authors!
It took me a long time to get invested into this book. I didn’t feel fully interested in the story until about halfway through which is longer than it has taken in the past with her books. I wonder if that’s because this is the first book in a series and not a standalone.
Once I got to the halfway point, I finished the book in one sitting!!! The magic was super fun and I really came to like our characters!! I can’t wait to continue the series especially after that cliffhanger!!
I received an advanced reader copy in exchange for an honest review.
Two favorites quotes!!
"You saved me." He was looking at her the way she sometimes looked at casting formulas— completely and utterly baffled.
"You're just giving away paper crowns?" Theo took the orange crown off and examined it. "Is it a holiday?"
"No," said Sorrel.
"Yes!" Dasan spoke over her. "It's Dasan-is-bored day and get-rid-of-scrap-paper day. So everyone who visits the library today gets a free crown.

I've never read a bad Millie Florence book. But this is 100% her best one so far.
From the moment I started reading, I fell in love with the world. From the magic system to the Cloud Library, it was the first fantasy world I've ever genuinely wanted to move into-despite having read a lot of fantasy, I have never felt that way before. (And I wish, with all my heart, that I could be a Mage!)
The story was beautifully written and beautifully paced. The characters were very relatable, and at multiple times in the story, I felt compelled to cry out (to the dismay of the people around me), "POOR THEO JUST NEEDS A HUG!" It was so sweet-and the ending! Argh!!! I'm not going to spoil XD, but I will say it makes you want to read the next book for sure.
Theo was my favorite character in the story (mainly because I like characters who make me want to hug them, hehe), but Sorrel was the most relatable to me. She gives the impression of "reckless joy," and that's because she truly is a happy, joyful person. But inside, she has struggles, too, and that's a lot like how I am.
Beyond the two main characters, the side characters were also developed well, and lovable (DASAN!!!), and the villain-oh my word. I won't even go on about Maeve.
Suffice to say, I loved this story! Even though I normally read YA, it's still on my list of top favorites, and I would (and already have, lol) recommended it to virtually everyone I know.
Thank you, Millie, for writing this story! You're my hero <3

MY FAVORITE BOOK OF 2025!
This story holds the perfect amount of whimsy, heart, humor, coziness, and adventure. The world is magical in every sense of the word. Perfect for anyone who loves Studio Ghibli, Harry Potter, The Mysterious Benedict Society, and the Wingfeather Saga. It's clean and very-well written, perfect for a middle grade audience.
I love this book so much :) (even though I'm 18 XD) I need the next book ASAP!! It was so good *cries from happiness*
Note: I received an eARC from the author in exchange for an honest review.

Ok. Book two can not come soon enough.
I absolutely adored this book. In my humble opinion, it is the best Millie Florence book yet.
Theo and Sorrel's friendship was beautiful. Dasan was a lovely side character (seriously, I love him).
I feel like anything I else say will be spoiler-y, so I'm just gonna leave the review as looking back on the first sentence.
(I thank Millie Florence for the eARC of this and for allowing me to beta read last year. All opinions and views expressed are my own)

Okay, so here is my full review! I received this book as an ARC reader in an exchange for an honest review! :)
This was one of the best books I’ve read all year.
I often find myself disappointed by middle grade books because often authors use it as an excuse to give readers a half baked plot with even worse writing, but this book was not one of those books in the least. It gave me a REALLY GOOD plot and ✨AMAZING ✨characters and the writing was BEAUTIFUL!! This may rival Honey Butter as my favorite Millie Florence book.
I just want to take a moment to comment on the experience of reading this book. Because this book had me staying up later than I should have to read the climax, feeling so aesthetic and cozy while reading it, and wanting nothing more than to reach into the pages and give the characters a hug.
It was just such a cozy middle grade read and I had so much fun reading it
I dont even know where to begin in terms of story and characters. Okay first off, Sorrel and Theo are so adorable and I love them. Their characters are written so well and I love their dynamic. Also their inner conflicts and emotions are so good.
Also, Dasan is possibly my favorite character in the entire book. I feel like he would be my best friend irl XD also his emotions at the end?? Aghhhhh so good.
Not to mention, the worldbuilding was AWESOME!! It was really creative and the magic system was one of my favorite parts of the book. Each setting was unique and fit the aesthetic of the story so well.
AND THE CLIMAX HAD ME HOOKED
I will admit, the beginning did feel a bit rushed, but other than that, the book was perfection. I LOVED IT SO MUCH!! NOW WHEN DO I GET BOOK TWO??

Such a delightful fantasy read!
The Apprentice Alliance, the first book in the Mage Pocket trilogy, is a great starting point for this new middle grade fantasy series...
Sorrel's parents were tragically killed in house fire that she is certain was no accident and she aims to prove it. Theo has been an apprentice to the Dark Mage since he was just 7 years old. After a terrifying mission, Theo begins to realize that he does not agree with the Dark Mage's quest for power and is desperate to find a way to break his apprenticeship. In a twist of fate, these two characters form an alliance to help each other accomplish both of their goals...but each of them is keeping secrets that will bring consequences to their blossoming friendship. They are both great characters that show a lot of emotion and growth over the course of the book... you really get invested in both of them! There are also some charming side characters that really round out the story.
The fantasy world of the Mage Pocket is well crafted. The magical world is interesting and whimsical, but not overly complicated/hard to follow. I especially LOVE the fun things like a library in the clouds with an elevator, library cards that magically transport you to the library, and the invisible cat named Marbles!
This book would be a great family read aloud choice. I also appreciate that this is a "clean" middle grade fantasy book, which makes it great for the whole family. I have read several other titles by Millie Florence, and this is her best work yet! Book 2 cannot come soon enough!
I received a complimentary advance reader copy of this book, however, the opinions expressed in this review are completely my own. Happy Reading!

Absolutely astounding. Millie brings a story with her usual charming yet deep writing style.
I ADORED this book. The characters were so sweet and followable, and the friendship between Sorrel and Theo was SO SWEET. The story and the themes were woven very thoughtfully.
It was more than just a fun romp (though it was that indeed) it was also a story with deeply personal themes about the battle between light and darkness (pictured quite literally in this book) and the hope of finding a new home and family.
Thank you to Millie for the ARC copy, it was definitely one of my highlight reads of the summer :D

A review from my 13yo:
Book one in The Mage Pocket Trilogy was delightful! From its vibrant characters to the witty bits of dialogue… even the little illustrations on each page were lovely.
I’m a thirteen-year-old (reviewing on my mom’s account) who reads a lot of middle grade fantasy.
Millie Florence likens this book to ones like Harry Potter, Keeper of the Lost Cities, The Wingfeather Saga, and The Mysterious Benedict Society, and I agree. This book fits perfectly on the shelf with other adventurous fantasy. It’s sprinkled with lots of whimsy and humor, but don’t let the invisible cats and floating libraries fool you- this book is much deeper than meets the eye.
It makes a perfect read-aloud, especially for those with older elementary to middle school kids, but really as a family. It’s the kind of book that engages all ages, speaks to them through the text, and grows in depth as they grow in understanding.
You can find the full content guide on Millie Florence’s website, but here is a
Brief Content Guide
Romance: None
Violence: Multiple chase and fight scenes, description of a broken thumb
Language: None, though some made up words and phrases used as exclamations and light/playful insults (“Zooks!” “ You bacon-brain!”)
Other: A magic system revolving around light and darkness, a character with memory loss, some scarier adult characters
This is the perfect book to read under a leaf-barren tree 🍂

*I got an early copy in exchange for an honest review* I've been following Ms. Millie for some time now, and oh my goodness, this book is one of her bessttt!(although they are all really good, XD). This story follows the tale of Sorrel, the suddenly orphaned daughter of some of her country's greatest leaders. In the Mage Pocket, where Sorrel lives, there is a floating library, an invisible cat, and magic drawn from the light(which, in this world, is just in the air). Unfortunately, Sorrel hasn't figured out how to cast, and at 12, is desperate to learn to finally find out how her parents really died.
Enter Theo, who is appertained to the dark mage, who killed Sorrel's parents. He's looking for a way to annul his contract with the dark mage, and hence, stumbles upon the cloud library, where he meets Sorrel, who agrees to help him find books to annul contracts in exchange for magic lessons.
The two quickly become friends, and when the dark mage's evil plans to destroy the Mage Pocket comes more quickly than anyone could have thought, the fate of their world rests on the Apprentice Alliance to save the day.
An epic MG fantasy combined with Millie's signature flare! Sure to be a quirky, whimsical fantasy read for anyone between 10 and 10000!

I have thoroughly enjoyed everyone of Millie’s books in the past and this was no exception. Although her others are wonderful, this may be the best yet.
I came into this book with almost no idea of what to expect, and it did not disappoint. The magic system was well thought out and I can’t wait to learn even more about it! This is a sweet and heart warming story yet it still felt deep. The main characters are struggling but when they meet they are able to help each other and a beautiful and sweet friendship ensues. Every character has a lovely personality (aside from the villain ofc, although she’s quite well written). This maybe be one of the best books I’ve read this year and I can’t wait for book 2.
(Im so thankfully to Millie for giving my a chance to read an eARC, all opinions and views are my own.)

This fantasy book by Millie Florence is an absolute treasure! Apprentice Alliance is full of adventure and magic, which I love, and Millie Florence's whimsical storytelling and descriptions are amazing! Apprentice Alliance is full of dynamic and loveable characters that you won't easily forget and has themes of friendship and fighting for what is true. You can visit a world where humans have been given the ability to capture the energy in the air and transform it into something magical. There is NOTHING I disliked about this book. Five stars, this was an incredible read. As a part of the release team for this book, I got to read it early, but in no way did that influence my review! :)
January 2, 2026
This amazing book opens the world of the Mage Pocket to the reader. The first book of the trilogy, it captures all the scenes and descriptions into itself. I couldn't drop the book the first time I read it. This enticing and exciting fantasy tale is my top read this year! I can't wait for the next books in the series. I highly recommend this for middle-grade readers. Keep going, Millie!

Absolutely fantastic middle grades fantasy with a clever magic system. I love how Millie Florence teaches the system and reveals the backstory gradually rather than front-loading the reader with information. Most importantly, she has written characters that I care about well before the end of the book. I need book two ASAP!

This is my new favorite MG book!
I knew I would love it when I read the synopsis/blurb, and it did not disappoint! The characters are so fun, and watching their dynamics is very entertaining. The themes and heavier topics like grief were handled well. The plot is engaging and the suspense kept me on the edge of my seat. I want a bookmobile or a magical library card that transports me straight to the library! This is an amazing book, and I highly recommend it! Thank you, Millie, for the ARC!

{387 print pages}
Genre: Fantasy, magic realism, middle-grade
Tropes: Secrets
Setting: A place eminiscent of the real world
Writing style: Dual POV, 2nd person, past tense
Tone: Alternately light-hearted, tense, and perilous
Character- or plot-driven: Character-driven, though I expect the rest of the trilogy to be more plot-driven at least.
Romance: No
Clean level: I appreciate that there is no rude or scatological humor, like there is in some books for younger readers.
Sensitive aspects:
• Grief from being orphaned
• Child forced to take part in murder
• Someone breaks a boy’s finger, blood with minimal description
Favorite aspects of the book:
• The characters
• The relationships
• The balance of action and character- and relationship-building
I enjoyed this start to the Mage Pocket Trilogy. It ends with a cliffhanger but one that doesn’t feel so much like you’re left hanging. Meaning, you’ll want to know what’s next, but not in an urgent way. The protagonists are 12-years-old, and while they are involved in doing things that most children would not be, some decisions and judgements they make feel age-appropriate. One of them makes a particularly foolish mistake, but it’s one you would expect from someone with that age level of critical-thinking skills and risk-taking tendencies.
Sorrel and Theo get along beautifully from the start and become the first real friend each has ever had. Sorrel’s 16-year-old cousin, Dasan, is like a big brother towards her and is generally good-hearted and jovial.
The theme that stood out as most central in this first book is the juxtaposition Theo sees between an alliance based only on how useful people are — what you can get out of them — and one that forms from reaching out in warmth and friendship, where those involved genuinely care about each other. Even Theo’s one friend among the other Dark Mage apprentices doesn’t have any real loyalty toward him. There’s no genuine concern in that place; any kindness shown is a farce meant to manipulate and maintain forced loyalty. In Pocketon, where Sorrel lives, Theo encounters people who are friendly and kind even to those they don’t know and seek nothing from. The relationships are real, and loyalty is a choice.
Favorite Quotations:
• His memories of the past were like a book someone had read through and inked out the passages they did not like.
• More hair had come loose from her braid, fluttering in the breeze like tiny tongues of fire.
• According to history, all humans were given the opportunity to create with the light of the world, but it’s up to them if they create, and what they create, for better or worse.
• “Do you know how to drive this?” “Do I?” Sorrel sat up straight and crossed her arms, puffing out her chest. “Zooks! I’ve grown up in the Cloud Library and ridden in here about a million times!” “Right.” Theo blinked at her. “So do you know how to drive it?” “I . . .” Sorrel hesitated, opened her mouth, and then closed it again. “No. No, I do not.”

WOW.
Just wow.
This novel was AMAZING.
It touched my heart in so many ways.
It’s like sunflowers and blackberries and sun shining through rainclouds. So sweet and warm and joyful and full of friendship and hurt and healing.
(*a few spoilers ahead!*)
The characters…breathtaking. I LOVE Sorrel and Theo…and Marbles too! Sorrel and Theo’s friendship is so beautiful-the way they come to trust and love each other (as friends!!!) is so amazing. They both have deep hurts, deep sorrows, deep wounds, and yet they struggle through it…together. They help each other heal…but a secret lies beneath the surface. A secret that could shatter their friendship forever.
The pacing was amazing! It was slow enough that you got to enjoy the characters growing closer together, but fast enough to keep you on your toes! The plot wound and twisted and rose and fell, and I kept gobbling up the story! And I *MIGHT* have stayed up *a little* too late to finish…I just kept saying “just one more chapter!” “just one more chapter!” “just one more page…” until I read the last words. I had to know what happened!
The writing is so lovely-and the character’s voices really stand out!
If I had to choose a favorite character, it probably be Sorrel-I love her stubbornness and determination, her soft moments and her bright laughter. But Theo…he’s so sweet and tortured and aaaahhh!!! he just needs hugs!
So-I ABSOLUTELY LOVE THIS NOVEL!!! I know I will be rereading it in the (very near) future, and I will get down on my knees and beg you to read it if I have to! (But I shouldn’t have to. Because you should be reading it right now!!!)
Thank you, Millie Florence, for writing this beautiful story. It’s such a blessing to this world!
Just wow.
This novel was AMAZING.
It touched my heart in so many ways.
It’s like sunflowers and blackberries and sun shining through rainclouds. So sweet and warm and joyful and full of friendship and hurt and healing.
(*a few spoilers ahead!*)
The characters…breathtaking. I LOVE Sorrel and Theo…and Marbles too! Sorrel and Theo’s friendship is so beautiful-the way they come to trust and love each other (as friends!!!) is so amazing. They both have deep hurts, deep sorrows, deep wounds, and yet they struggle through it…together. They help each other heal…but a secret lies beneath the surface. A secret that could shatter their friendship forever.

Fantastic! I love a book where the onion is peeled slowly. I don't mind being pulled in slowly, because it makes the rest of the book that much more thrilling. The plot and characters are great, and I can't wait for the 2nd book.

I received this book for free as an ARC reader. I Loved this book!!! I can’t wait for the next one. The character development was fantastic and I just want so much more.

This is the second time I’m going to write a long, rambling review of a Millie Florence book.
And this time it’s not just going to be correcting the Latin.
(by the way, you can read my review of Beyond Mulberry Glen, which I did, in general, like, just not as much as this book, here)
Zooks, I loved it so much. This is one of those series, along with The Incorrigible Children of Ashton Place, The Wingfeather Saga, and the James Ponti City Spies/Framed books, that I wish I had read around the target age (9-12, basically, though this one could run older) instead of as a teenager. Here’s all my thoughts:
THEO. 100% my favorite character. I’m adopting him as my fictional child/little brother/something because he is precious and traumatized and needs a family. “I’m fine,” no honey, you are not. This kid needs to be wrapped up in some blankets and given a cup of tea and a book and be told to just stay there for a while and not be overwrought by guilt over things that really weren’t his fault and…
I love Theo, okay?
SORREL. My second favorite character. Also precious. Not adopting her because she doesn’t need a family and also I kind of ship her with Theo so it would be weird if they were siblings. Sorrel’s also the one of the two who’s more like I am. I mean, I kind of wish I was a Theo, but I know I’m a Sorrel. (I mean, I set a napkin on fire with a candle one time just to see what would happen. Recently. Girl and I are kindred spirits).
Shipping aside, though, because I know that probably wasn’t the intention, their “alliance” (friendship) is the cutest thing
MAEVE. Great villain. Felt like a good three dimensional character. One of the quibbles I had with Beyond Mulberry Glen was that besides the main character, the others seemed pretty typical/two dimensional. Charming, but still not very dynamic. That’s not true at all within this book, and Maeve is the best example.
My major problem with Beyond Mulberry Glen was the blatantly incorrect Latin sprinkled through that one. The only Latin in here that I can think of is “lumen” the word for the light the magic system is drawn from, which isn’t incorrect, so yay!
Speaking of the magic system, I loved it. It’s interesting and yet simple enough for middle grade readers. It’s basically you draw light from things like the sun, the moon, or other people (if you’re a Dark Mage), and use it in different spells that have various levels of difficulty. For my Cosmere friends, it definitely could comp to the magic system in Stormlight, just very simplified, and the light comes from different sources.
Oh, also DASAN. Love him! Love the Bookmobile! Would live on the Bookmobile!
The official promo stuff says this would be a PG-13 movie, which I disagree with. The major concern is the violence, and the most violent thing I can think of is that a character gets pretty injured in combat training, but even that I think would warrant a PG. So, even though the official age is 10-14, I would definitely give this to a nine year old, even an eight year old depending on their reading level (I would give this to myself at eight years old, for example, but probably not to the eight year old I nanny, only because it’s more of an advanced reading level than she is at. It would maybe work as a read aloud)
K, so more on the violence, actually (because I wrote the first part before I read the climax. There’s a slightly disturbing scene where Still think it’s PG, but that’s worth noting.
There’s also this amazingly suspenseful scene where a character is sneaking around where he’s not supposed to be (for good reason) and doesn’t have that much time…and I can’t really describe it without giving the rest away, but it was so well written and honestly one of the highlights of the book for me.
Cool worldbuilding thing that I love: the characters use the old versions of names for the days of the week (Sun’s Day, Moon’s Day, etc) and it’s so cool and fun.
List of adorable characters: Maylee, Pippa, Marbles the cat (Marbles is also the best name for a cat and I love Dasan even more for coming up with it)
The last 90 pages or so are a complete roller coaster of a climax and I just couldn’t stop reading. The suspense is thrilling, and both of the main characters have development during the last couple of chapters, but Sorrel especially takes a major turn in her arc in the last couple of chapters and it’s shocking but amazing.
And it ends on this amazing cliffhanger/twist, too, ahhh, I already can’t wait for book 2, even though I got book 1 three months earlier than everyone else.
Also, random, but I really loved the acknowledgements. I usually read acknowledgements and don’t think much of them, but these are just so heartfelt and beautiful. It reminded me that even though this book isn’t explicitly Christian (even less so than Beyond Mulberry Glen), it has really Christian themes without any theological muddling by the book trying to appeal to secular audiences, too, and that’s hard to do.
My Few Criticisms:
I feel like Theo’s stomach twisted WAY too many times.
There were a few sentences that felt kind of run on, or, at least, they could have been expressed more clearly.
That’s pretty much all I could think of.
The sad thing about the way publishing works is that sometimes indie books can have a hard time taking off as well as those published by the Big Five do.
I hope this takes off, anyway. Because it deserves it.
As a young writer myself, Millie Florence is my personal hero.
And this time it’s not just going to be correcting the Latin.

[4.5 stars, rounded up]
This is my second Millie Florence book but definitely my favorite. This fantasy MG novel strikes the perfect balance of being entertaining for young readers and nuanced for older readers (which I guess includes me now XD). Obviously I can’t speak for younger readers. However, I CAN say that I would wholeheartedly recommend this book to any reader, middle-grade or otherwise, looking for their next fantasy read.
There are a lot of things I could say about this book: its worldbuilding is reminiscent of Septimus Heap, but with a focus on libraries; it’s angsty without being too dark or graphic; a vanishing cat is a recurring character; the writing style is simple but powerful. Yet my absolute favorite part of the book deals with the complicated character dynamics, especially those between our two main characters, Sorrel and Theo. Both characters are fully fleshed out and jump off the page, but it’s the subtle ways they interact with each other and think about each other that really shone for me. Add in a villain who is simultaneously 100% on the side of evil and yet is not fully evil herself (she kind of loves people! kind of!), and you’ve got me fully invested.
I’m so, so excited for the next book in the series—especially after that AWFUL cliffhanger XD. But in the meantime, I’ll definitely be rereading this one in the near future! I miss these chaotic characters already.

This is a beautiful book! The writing was amazing, and the story was beautifully written.
Premise:
When Theo's mentor, the Dark Mage, brings him on a mission to kill the Heads of the Mage Council, Theo realizes that he cannot serve her cause. The Dark Mage claimed to bring justice, but justice cannot come from killing the innocent.
Sorrel is the daughter of the Heads of the Mage council. When her parents die in what grown-ups tell her was a terrible accident, she realizes that she needs to learn magic in order to figure out what actually happened to her parents.
When the two unexpectedly meet, they decide to form an alliance. An Apprentice Alliance. In return for information and access to the books he needs in order to break the contract with his mentor, Theo offers to teach Sorrel magic.
The Apprentice Alliance is a great book, the author did such a good job handling the characters! It was a perfect balance of real life and whimsey. 5/5 Stars, I would give it ten if I could.

The first thing I loved about this book was the worldbuilding. Everything is whimsical and comforting, astonishing and yet believable. The library, the caves, the city, every place drew me in. The magic system was brilliant and well-explained.
The second thing I loved about this book were the characters. I laughed and mourned with Sorrel, who reminds you that the best things are worth trying for. I held my breath with Theo, hoping beyond hope that he could find friendship and heal.
Although the book does start off slower, it gave me time to get to know and love everyone. Then, when the action really started building, I could feel my pulse race faster with each tense scene.
Finally, there was the cliffhanger, which was also very well done. Everything seemed so neatly wrapped up... and then... let's just say that the next book can't come soon enough.

I read this book *so fast.* Theo & Sorrel's friendship was so endearing, and refreshingly platonic. The world felt so whimsical (floating libraries and magic library cards!), and both main characters were sympathetic and relatable. Theo is my favorite though - he is a precious cinnamon roll and he deserves a happy ending.
Speaking of ending, I won't spoil anything, but AAGH! It felt like the floor dropped out from under me as the realization kicked in! I cannot WAIT for the second book! Five stars all the way.

Thank you for my advanced copy!
I wouldn't have normally reached for a book about magic, but I loved Millie's last book (Beyond Mulberry Glen)! The Apprentice Alliance is a really fun adventure story, and I am looking forward to the sequel. It did take me a little bit to get fully invested in the story, and I was a little confused on a few points in the world, but once the story picked up, it was easy to keep reading. The character development wasn't as solid as I expected, but it was a fun adventure with likable characters.

A magical, riveting tale full of whimsy and adventure 👒🌿
I loved the perspectives from both Sorrel and Theo, and I was so quickly invested in their lives and their desires! I also loved all the sweet side characters, especially little Maylee (and her friend Pippa) 🥰
The plot was tense at a lot of points, and that cliffhanger at the end just about killed me... (I need the next book pronto!!!) But the author does a wonderful job at balancing the tense moments with more lighthearted ones!
I cannot wait to read the rest of this trilogy 😆

A great fantasy, caught my attention as soon as I read the first line. This book is a great solid choice if you love adventure, fantasy, and a great fun read! You'll root for the characters the entire way through the book, watching as they grow and change into a better character! Five stars for sure!

That was honestly a really fun romp! I liked Theo better than Sorrel, poor traumatized boi. It's a great book for younger readers, and I loved the magic system, fleshed out characters, and the heart of friendship!!
I received an ARC from Millie, but this doesn't affect my review. Also, sorry this took so long to get the review up XD
