Sophie Foster is struggling. Grieving. Scrambling. But she knows one thing: She will not be defeated. The Neverseen have had their victories - but the battle is far from over. It’s time to change tactics. Make sacrifices. Reexamine everything. Maybe even time for Sophie to trust her enemies. All paths lead to Nightfall - an ominous door to an even more ominous place - and Sophie and her friends strike a dangerous bargain to get there. But nothing can prepare them for what they discover.

Sophie Foster wants answers. But after a lifetime of lies, sometimes the truth is the most dangerous discovery. Even the smallest secret comes with terrifying new responsibilities. And Sophie’s not the only one with blank spots in her past, or mysteries surrounding her family. She and her friends are part of something much bigger than they imagined - and their roles have already been chosen for them. Every clue drags them deeper into the conspiracy. Every memory forces them to question everything - especially one another.

Sophie Foster is back in the Lost Cities - but the Lost Cities have changed. The threat of war hangs heavy over her glittering world, and the Neverseen are wreaking havoc. The lines between friend and enemy have blurred, and Sophie is unsure whom to trust. But when she’s warned that the people she loves most will be the next victims, she knows she has to act. A mysterious symbol could be the key - if only she knew how to translate it. Every new clue seems to lead deeper into her world’s underbelly and the Black Swans aren’t the only ones who have plans. 

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 listeners 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. 

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.
