It’s been weeks since Mena and the other girls of Innovations Academy escaped their elite boarding school. Although traumatized by the violence and experimentations that occurred there, Mena quickly discovers that the outside world can be just as unwelcoming and cruel. With no one else to turn to, the girls only have each other - and the revenge-fueled desire to shut down the corporation that imprisoned them.

The girls enroll in Ridgeview Prep, a private school with suspect connections to Innovations, to identify the son of an investor and take down the corporation from the inside. But with pressure from Leandra, who revealed herself to be a double-agent, and Winston Weeks, an academy investor gone rogue, Mena wonders if she and her friends are simply trading one form of control for another. Not to mention the woman who is quite literally invading Mena’s thoughts - a woman with extreme ideas that both frighten and intrigue Mena.

And as the girls fight for freedom from their past - and freedom for the girls still at Innovations - they must also face new questions about their existence...and what it means to be girls with razor hearts.
