Angie Thomas' #1 New York Times bestselling fantasy trilogy comes to a thrilling conclusion as Nic Blake makes a perilous journey through the Remarkable world-whether to save it, or to destroy it, she does not yet know.

Nic Blake is finishing her first year of Manifestor school, but the Remarkable city of Uhuru still doesn't feel like home. Between her secret prophecy (the one that says she will destroy the Remarkable world), her secret power (the one she still can't control) and everything happening with her best friend, JP (who hasn't been around since learning he was a prophet), Nic can't help but feel like she's living in hiding. And, that the only thing worse than hiding her secrets will be the moment when the world finds out who she truly is.

That moment, however, turns out to be even sooner than she feared. The tensions that have been rising between LORE and Remarkable cities across the country suddenly explode into open war-an attack on Uhuru in which Nic has no choice but to save everyone-and in doing so, reveal her powers to all. But when Nic is called before the council to be questioned, something extraordinary happens: Nic and her twin brother, Alex, are pulled into some sort of vortex, and when they emerge, everything is as it was before the attack.

Well…not everything.

Nic and Alex soon discover that what happened to them was the result of someone altering things in the Time Realm. Nic and Alex can only guess who or what is behind it; the one thing they know for certain is that, if they want to restore history, it's going to be up to them to travel through time to do it. But it's a journey that will find Nic asking herself: Is returning everything to the way it was truly what's best for her, her family, and the Remarkable world?
