Sophie battles the rebels—and recovers dark memories from her past—in this jaw-dropping fourth book in the bestselling Keeper of the Lost Cities series.
Sophie Foster is on the run—but at least she’s not alone.
Her closest friends from the Lost Cities have gone with her to join the Black Swan. They still have doubts about the shadowy organization, but the only way to find answers is to start working with them. And as they settle into their new lives, they uncover secrets bigger than anything they’d imagined.
But their enemies are far from done, and unleash a terrifying plague that threatens the safety of an entire species. Sophie and her friends fight with everything they have—with new allies joining them—but every choice has consequences. And trusting the wrong person could prove deadly.
In this game-changing fourth book in the Keeper of the Lost Cities series, Sophie must question everything to find a truth that will either save her world—or shatter it.

Best book in. The. World.
I absolutely love your books they are all full of of excitement and always make me want to turn the Paige now I’m only twelve but I love this series I was literally crying in book three and four my friends and teachers are also telling me to put my book away because I keep reading it but honestly I just can’t stop reading thank you so much for writing this book and please keep up the good work I can’t wait to read legacy your eighth book either. PEACE ✌🏾
I love this series!
Thanks for creating the series Shannon Messenger!
This is as good as Harry Potter
Favorite book in the series!
This in my opinion is the Shannon Messenger’s best work. It had character development and suspense, and was written with skill. The plot line was thick and complimented the other books in the series very nicely. The tense story line is often filled with comedic relief (a nice touch, Shannon). Overall, I think that Mrs. Messenger really outdid herself on this one, and it will be an enjoyable read for any KOTLC fans!!!
