"In this extra special installment of the Keeper of the Lost Cities series, the story picks up right from Legacy's particularly devastating cliffhanger. But chapters alternate between Sophie and Keefe's perspectives to give readers deeper insights into both beloved characters. New powers will be discovered. Hard truths from the past will come to light. And all of your favorite characters will find themselves tested in ways they never imagined"-- Provided by publisher
