Lunamancer description:

Returning to his hometown in Upstate New York, Dr. Issac Blake senses his estranged sister is in trouble. Driven by an unseen force, Issac steals a car, acquires a crowbar and breaks into her house - but she's missing. And no one's noticed. Issac methodically tracks his sister's disappearance to a mysterious local who can draw reality-altering powers from the moon itself - the Lunamancer.
