For as long as Rivera Ardis can remember, child and teenaged insurgents known as “peace rebels” have bombed America in a never-ending conflict, triggering endless curfews and suspicious glances directed at anyone under the age of nineteen. Now it’s 2083, and River wants nothing more than to join the elite counterinsurgent task force to help end the war, but when she’s accidentally flagged by the Reprobate and Extremist Division, those dreams are called into question.

Desperate to prove her loyalty, River chooses to shadow Tony Ryder: a reclusive boy with suspicious family ties to the peace rebels. Catch him in a crime, and she reclaims her future.

In 1995, Cherith Brook knows nothing of the future, and that’s the problem. But her father’s time machine could change all of that. Together they could prevent wars, stop attacks, and never fear what a new day brings. Yet there’s one attack Cherith never saw coming—one that changed the course of history and left her stranded in a future she doesn’t recognize.

While Cherith scrambles to return home, River hunts for the RED’s approval and Tony resists the government’s scrutiny. It’s going to take all three of them and their radically different views to correct a terrible mistake in the timeline. But can they trust each other? After all, the temptation to control time for personal gain is too strong for anyone to ignore.
