I’ve seen SO many MG series calling themselves the next Harry Potter, but very very few deliver on the promise. Messenger succeeds with Keeper of the Lost Cities because rather than trying to actually be the “next Harry Potter,” she’s offered a completely new and equally engaging world to explore. Take a look at the blurb, then read on to find out why it’s a must-read for tweens this summer.
Get hooked on the New York Times-bestselling series that’s taking the world by storm!
When Sophie Foster discovers she’s an elf from the Lost Cities, she embarks on an incredible adventure, discovering new abilities, and making new friends. But the secrets of Sophie’s past were buried for a reason and the truth she uncovers could put all of the worlds in danger.
As mentioned above, the series currently includes 7 books, with an 8th one releasing just in time for the holiday season. Here they are in order:

What makes Keepers of the Lost Cities the must-read series of the summer?
First of all, Keeper of the Lost Cities is that rare gem of a series that is both girl and boy friendly. Like Harry Potter, Sophie has a diverse group of friends, so tweens are pretty much guaranteed to see themselves in at least one of the characters. Fans of Hermione Granger will definitely adore Sophie Foster. She has the same bravery, intelligence and complexity that made Rowling’s heroine so appealing.
Tweens and teens who adore a good love triangle won’t be disappointed, either. Sophie has two main love interests and many fans root for one or the other, considering themselves either “Team Keefe” or “Team Fitz.” Since the series begins when she’s 12 and continues over the course of a few years, readers get to see the love triangle grow and evolve naturally. If your tween isn’t really into love stories, don’t worry: it’s a secondary plot. You won’t see Sophie go catatonic just because a boy didn’t pay adequate attention to her. 😀
Although the setting is otherworldly, the themes are things that all tweens can relate to. Some of the major themes throughout the first 7 books include:
- Feeling different, like you just don’t belong anywhere, like you’re a “freak”
- Dealing with secrets and knowing who to trust
- Helping those who are different from us or who need it the most
- Discovering that family isn’t always about who you’re related to
- Learning to find yourself outside your family’s expectations, and that it’s okay to be different
Like other successful middle grade series (Harry Potter again, pretty much anything by Riordan, etc), the moral and ethical lessons aren’t thrown in your face, but rather discovered through great storytelling. In other words, Messenger doesn’t just repeat “It’s okay to be different,” but rather shows you a strong set of characters who make this discovery throughout their journey.
While the series is geared towards tweens, like all the best MG fantasy series it’s also a fun read for adults. I suggest reading it along with your kids and discussing it together, a la family book club style!
It’s easy to see why Keepers of the Lost City has over 1 million books in print worldwide, and why Shannon Messenger has such a devoted fanbase. FYI, she shares a lot of great content on her Instagram page, including character art, teasers for upcoming installments, answers to fan questions, and more.
