Ella isn't anyone's pet anymore, but she's certainly not free.

After exposing the dark secrets about NuPet's breeding program, forcing them to repeal the law that allowed genetically modified girls to be kept as pets, she thought girls like her would finally be free. But she never dreamed that it would backfire. NuPet may have convinced the public of their intentions to assimilate pets back into society, but Ella knows it's a lie.

They aren't planning mass rehabilitation - they're planning a mass extermination.

Now, with the help of a small group of rebels, she's set on finding a way to bring down NuPet for good. But when her group gets implicated in a string of bombings, it becomes clear that none of them are safe - not her, not Penn, not even his family. And with the possibility of a spy planted somewhere in her group, there's no way to know whom she can trust. If she can't untangle the web of blackmail and lies that extends far beyond NuPet's reach, she won't just lose her chance at freedom, she'll lose everyone she loves.
