It was Julian’s last challenge before he disappeared into the Shadow World, taking Jenny Thornton’s boyfriend Tom and her cousin Zach: “If you want them, come on a treasure hunt. But remember: if you lose, there’s the devil to pay.” Jenny, Audrey, Michael, and Dee have burned their bridges, leaving their families behind, to enter the Shadow World with a set of runes, magical letters that open the doors of hell. They’re lost in an amusement park nightmare, at Julian’s mercy as they look for Tom and Zach. Jenny’s only clue is a gold coin, Julian’s gift, and Julian himself, more beautiful, more seductive, more dangerous than ever. And determined to make her his bride. . . .
