The Black Tattoo (Standard format, CD)

Jack's best mate, Charlie, has always been effortlessly cool. When Charlie wakes up one day and finds a mysterious, moving black tattoo on his back, it's a clear sign that he's even cooler than Jack thought. To top it off, Charlie has got super powers also.
Or does he?
Jack soon learns the terrifying truth: Charlie's incredible powers come from an age-old demon called the Scourge, who is using Charlie to bring about its evil master plan.
When the Scourge vanishes with Charlie, Jack and Esme, a girl with super powers of her own, follow their friend from the streets of London into Hell itself, where they face horrors that may well cost them their lives.
