The world is divided. On the Continent, you’re either a Prime—immune to the biotoxin that nearly wiped out the Earth’s population 150 years ago—or a Modified, one who was enhanced by the toxin, developing powerful psychic gifts. As conflict rages between the two sides, Wren Darlington lives in hiding. Occasionally running the odd op for the rebel Uprising against the Primes’ oppressive rule, she must keep a low profile. After all, if the enemy finds out that she is a Mod with a staggering four psychic abilities, she won’t just be sent to the labor camps. She’ll be executed—immediately and without trial. When a careless mistake puts Wren in the crosshairs of the Continent’s military, she is taken captive and forced to join their most elite Silver Block. Unwittingly, they’ve handed her the perfect opportunity for the Uprising to strike a devastating blow from inside their ranks. That is, if she can keep her powers hidden, survive training, and prove herself to Cross Redden, her maddeningly cocky commanding officer.
