Keeper of the Lost Cities — Reading Order

Shannon Messenger's Keeper of the Lost Cities series is a middle-grade fantasy phenomenon. Sophie Foster has always felt different — she can read minds, has perfect memory, and has never quite fit in with humans. When she discovers she is actually an elf who was hidden in the human world as a child, Sophie is whisked away to the Lost Cities, a dazzling hidden civilization of elves, and enrolled in Foxfire, an elite academy. But her mysterious past and unique abilities make her a target.

Read the series in order starting with Keeper of the Lost Cities. With nine main books plus two half-step volumes (Unlocked and Unraveled) that continue the story, it is a substantial commitment, but each book builds on the relationships and mysteries of the previous ones.

Messenger has created a richly detailed world with creative magic systems, compelling mysteries, and a large cast of characters that young readers become deeply attached to. The series handles themes of identity, belonging, and the pressure of being "the chosen one" with sensitivity and nuance. The romantic subplots are age-appropriate and well-handled, and the expanding cast of friends and allies keeps the dynamics fresh.
