Detox — Michael Dunn

The age-old story of boy meets girl, boy loses girl, boy tries to get girl back, but the boy is a bi-polar alcoholic, the girl is a heroin addict, and the plan to get her back involves kidnapping and ketamine-and an insistent nosy neighbor hell-bent on getting into the house. As the withdrawal mounts, Mat forgets his meds, forcing Julia to fight to survive against bad trips, Mat's downward spiral and a mysterious watchman who haunts the gloom, while Mat unwittingly risks her life to win her back.
