Twenty-year-old Wren Darlington is not your ordinary Mod. She’s one of the most powerful in existence.But her world is divided. On the Continent, being a known Modified means certain death, as the Primes—those immune to the biotoxin that nearly wiped out the population 150 years ago—want nothing more than to eliminate those who were enhanced by the toxin and developed psychic powers.Wren has survived all these years by concealing her abilities and keeping a low profile while doing what she can to aid the rebel Uprising in fighting against the Primes’ oppressive rule. But one careless mistake places her in the crosshairs of the Continent’s military, and she is forced to join their most elite program: Silver Block. Unwittingly, her enemy has given her—and the Uprising—the perfect opportunity 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 cocky, maddeningly attractive commanding officer.Despite the explosive chemistry between them, Wren cannot let Cross get in the way of her mission. But as war rages between Mods like her and those who aim to destroy them, emotions run high and secrets are revealed, forcing Wren to decide how far she’s willing to go to protect herself . . . and how much of the Continent is worth saving.
