Faker, by Mike Carey and Jock

A terrific high-concept – five friends wake up after a night of hard partying to find a sixth friend who they all remember, but was never there before – undermined by a weird plot about secret government weapons and a heroine who is entirely unlikeable and unredeemed. Too bad; I wanted to love it.
