Triad Blood. Triad Blood Trilogy, #1

The law of three is unbroken: three vampires form a coterie, three demons make a pack, and three wizards are a coven. That is how it has always been, and how it was always to be. But Luc, Anders, and Curtis-vampire, demon, and wizard-have cheated tradition. Their bond is not coterie, pack, or coven, but something else. Thrust into the supernatural politics ruling Ottawa from behind the shadows, they face Renard, a powerful vampire who harbors deadly secrets of his own and wishes to end their threat.
The enemy they know conjures fire and death at every turn. The enemies they don't know are worse. Blood, soul, and magic gave them freedom. Now they need to survive it.
