Grafts of animal skin have replaced tattoos in popularity, which gives rise to a unique new demographic: xenofreaks. Bryn Vega's father is head of the Pure Human Society and when she's kidnapped by the Bestia Butcher, the most notorious of the criminal xenosurgeons, she assumes it's payback for her father's anti-xeno activities. Scott Harding is her taciturn jailer-called Cougar because of the claws replacing his fingers-but Scott is not who he seems. Deep under cover for the Xenofreak Intelligence Agency, he's been given unprecedented immunity to find the Bestia Butcher's lair and do whatever it takes to bring him to justice. When Bryn is forced to undergo a radical xenoalteration, she discovers a terrible secret: her father is using The Pure Human Society as a front for his own purposes. His willingness to sacrifice his daughter to accomplish them sends her running to Scott for protection, and into the hard-core underground subculture of the very xenofreak society she once despised.

Riot-torn New York City is a dangerous place to be, especially if you're a xenofreak.
