Jack doesn't know what he's got himself into. One minute he and his best friend Charlie were up in Chinatown having crispy duck with Charlie's dad (and Jack was having to listen to Charlie shouting at his dad for leaving his mum) - then next minute they were in a mysterious room above a theatre, with some of the strangest characters they'd ever encountered. And they were about to take The Test. . . and something very very weird was about to begin. The Test transforms Charlie - leaving him with the distinctive markings of the Black Tattoo - and with a temper that seems out of control. The boys' meeting with Esme, a young girl with the most impressive martial arts skills this side of Bruce Lee, her huge and hairy father Raymond, and the mysterious Nick seem to have swept Charlie and Jack into a world they had no idea existed. And it's only going to get stranger. . .
