Sociopath. Killer. Deviant.
Monster, devoid of morals, incapable of human emotion. The villain known as Spark has been called this and more, and as a super-powered aberrant has masterminded countless crimes to build his father's inhuman empire. Yet to professor Sean Archer, this fearsome creature is only Tobias Rutherford—antisocial graduate researcher, quiet underachiever, and a fascinating puzzle Sean is determined to solve.
But one kiss leads to an entanglement that challenges everything Tobias knows about himself, aberrants, and his own capacity to love. When his father orders him to assassinate a senator, one misstep unravels a knot of political intrigue that places the fate of humans and aberrants alike in Tobias's hands. As danger mounts and bodies pile higher, will Tobias succumb to his dark nature and sacrifice Sean—or will he defy his father and rise from the ashes to become a hero in a world of villains?
