Lai, Jay, Al, and Erik are on the run after the military accuses them of being traitors. Tensions between everyone are high, but they have to stick together if they want to survive. And somehow stop the war that's now in full swing.

But when Erik returns to the rebels to find answers about his past, Lai, Al, and Jay have no choice but to go to the Order—a peace coalition bent on stopping the rebels and dissolving the enmity between gifted and ungifted. However, the longer the war drags on, the more Lai's long-kept secrets threaten to destroy everything she's ever worked for. Sparks fly as the team constantly questions whether they can trust one another and everyone tries to navigate a war that will change everything.

Filled with the same high-stakes superpowered action and complex relationships as A Soldier and A Liar, Caitlin's first book, An Outcast and an Ally brings this story to a dramatic and satisfying close.
