Sascia has always loved the Dark. Six years ago, when the world she knew collided with the world of the Dark, she found it thrilling rather than terrifying. Now, she spends her days studying Darkcreatures or seeking them out in the shadows where they thrive.

Then, one day, she—impossibly—pulls a person from the Dark. A person who shouldn’t exist. And they’re here to kill her. Nugau, the heir to the Darkworld, claims to be delivering a sentence for Sascia’s betrayal in a battle she’s never heard of, in a war that hasn’t happened.

Sascia escapes with her life—barely. But tensions are brewing between her world and the Dark, and it’s not long before she discovers that she and Nugau are bound together by forces they don’t understand. As they grow closer, crossing worlds and timelines, they must find a way to fight for peace—and for each other.
