Book 4, Keeper of the Lost Cities

This book can be downloaded and read in iBooks on your Mac or iOS device.


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.

Customer Reviews


I loved the first three books that you wrote and in can't wait to read the fourth😄

I'm in love with this book series!!!!!!

I have to admit I'm a book worm. The first three books have made magic come to life for me, they transport me to a place where my mind can get lost in the story and my wild imagination makes it come to life. Sometimes when I read these books I end up closing my eyes and rewriting myself into the story. I have read the first book so many times that the cover is coming apart. I love how much this series has inspired me, it inspired me so much that now I am writing my own book, with one of my closest friends.

Can't wait!!!

I love the series and have read all the other books a lot. U wouldn't even know I have read them more than once because they basically look brand new. I so bored right now because I'm waiting for
a bunch of other books to come out. I wish there was a way to put the whole series into one giant book even though I would have it done in a week or maybe less!
