Psychologist Mick Callahan, flawed hero of Harry Shannon's taut thriller "Memorial Day", wants to escape his violent past. He's finally back in the game, with a successful radio show, a new girlfriend and money in the bank. And then along comes Mary, the young drug addict who saved his life in Dry Wells. Mick Callahan is the kind of man who pays his debts, even if that means putting everything on the line. When Mary is abducted from his home all hell breaks loose. Callahan gathers his eccentric friends, sets out to find her and ends up confronting a gang of vicious psychopaths at Nevada's bizarre Burning Man Festival.
