Silver Elite by Dani Francis (Silver Elite, 1 of 2)

In the first book of a searing new dystopian trilogy, a young woman must conceal her psychic powers-and her attraction to her handsome, infuriating commanding officer-as she works undercover to take down a brutal government from within. 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. Despite the explosive chemistry between them, Cross doesn’t trust her-even as he seems determined to destroy the remaining shreds of Wren’s self-control. Yet as the war between Primes and Mods escalates, and as Wren and Cross find themselves unable to stay away from each other, they must decide how far they’re willing to go for their secrets-and how much of the Continent is worth saving.
