The Disciple — Susan Laine

Sequel to Fireworks & Wild Cards
The Wheel Mysteries: Book Four

Gus Goodwin witnesses a young man acting strangely at his occult shop -- and a day later the same youth is found brutally murdered at a secluded Radical Faerie sanctuary in the mountains. Gus and his private detective boyfriend, Niall Valentine, once again find themselves in the middle of a murder mystery.

First to cross their path is Professor Alex Kittridge, Gus's ex-boyfriend. Then into the picture stumbles Autumnsong, the biggest enigma they've ever encountered, to complicate the already confusing case. As Gus and Niall try to decipher the meaning of the cryptic poems left at the murder scenes, their pasts not yet laid to rest put a strain on their relationship.

Gus and Niall must uncover a slew of secrets within a spiritual group of queer social rebels before the vile killer strikes again -- or the investigation could very well end up being their last.
