The Paradise Trap — Catherine Jinks

A boy . . . a witch . . . and a totallysinister paradise: that's what Marcus gets when his mom rents a scuzzy trailer and parks it near a dirty, noisy beach. Some vacation! Marcus would rather play video games anyway, but when he discovers a staircase underneath the trailer, it looks as if he may be in for some kind of multilevel, multiplayer experience controlled by a complete nightmare of a witch. It's just like a game -- except it's all too real.

The author of Evil Genius spins a brilliantly compelling yarn of a journey into a dark and twisted land -- because once you enter the Paradise Trap, there's no guarantee that you'll ever leave!
