Two opposing factions of time travelers vie for control of the future in this thrilling steampunk series opener dubbed “Interesting” and “Unexpected” by Kirkus Reviews.
Lex and Ember—two time travelers with no memories of their lives before being recruited into the time war—are torn between the factions. When Lex accepts a mission that lands him deep within the heart of the Telsa Institute, he meets Ember, and the past that was stolen from them comes flooding back. Now armed with the truth of who they were, Lex and Ember must work together to save the future before the battle for time destroys them once again.
