Fugue

Eric—part-time King, quasi-avatar, and unconventional wizard—has an epic quest before him. He must return to his lost kingdom to save it, slay a creature claiming to be a god, and navigate the terrible risks of a paradox that could undo everything! And to top it off, he's trying to raise a daughter. Nobody said being a vampire was going to be easy, but none of this was in the brochure! "Fugue" is the seventh book in the "Nightlord" series, following "Nightlord: Mobius."
