Detective Gus Collier and his partner Jack Barnes solve crimes in Portland, Oregon, but that's just the surface of Gus's responsibilities. He's also the seventh child of a seventh child, giving him paranormal abilities and a second partner, Sarah Allen ... who just happens to be a ghost. A ritual murder during the ancient feast of Lammas, or First Fruits, will require all of Gus's talents (mundane and paranormal) and both of his partners (living and dead!) to solve. Will Gus and Ghost find the answer in time to prevent a city-wide disaster?
