The series follows Cal, a man that is half-monster and half-human. His mother was impregnated by an Auphe, a bloodthirsty creature also referred to as a "Grendel". The series begins with Cal and his brother Niko living in New York City, struggling to keep Cal's heritage a secret as they battle to survive those that would see them dead. Later novels deal more heavily with Cal's attempts to balance the dark nature of his father's race with his impulse to protect and defend others against the supernatural.
Caliban "Cal" Leandros
Caliban is the result of his mother mating with an otherworldly creature, a Grendel (Auphe). He is, as Thurman describes him, "half-human, half-monster, and all attitude." Cal inherited his Greek-Romani mother's raven hair, but has the pale skin of his father. Technically, Cal begins the books as 17 years old, but he was once kidnapped by the Auphe and spent two years in their home dimension called Tumulus, making him 19, since time in that placed follows different laws than on Earth.
