More about the book

Marco McGann's lost his job, his home, his girlfriend, and his mind. When he wakes from a drug-induced nap to find a man ransacking his apartment, he snaps and vows to take control of his life. And, more importantly, convince his ex Sarah to take him back. Marco's desperation, and a series of red herrings, leads him to believe that Sarah's been kidnapped. So, like a coked-up Philip Marlowe groping around in the dark, he sets out to save her.
