After blowing her cover as a double agent within Silver Elite and fleeing the Prime-controlled capital, Wren Darlington is finally safe behind allied lines. As her lover and former commander Cross Redden works to disrupt the Primes from inside their ranks, Wren turns her focus toward assisting the Uprising in overthrowing their rule once and for all.

Though she's back among her own people, trust is hard-won and hidden agendas abound on the Mod base. And beyond those walls, Wren can't help but worry that Cross is keeping secrets of his own . . . secrets that could jeopardize everything. Complicating matters even further is her shocking reunion with hotshot fighter pilot and undercover operative Grayson Blake. Once her closest friend in Silver Elite, Gray seems to understand Wren on a level she never thought possible.

With the war between Mods and Primes growing more brutal by the day, and with her own role in the conflict becoming more essential than ever, Wren must confront some gut-wrenching questions. Who is she fighting for . . . and who is she willing to lose?
