A rock 'n' roll band to die for . . . When fourteen-year-old Callie McCallan scores a backstage pass to interview the lead singer of the famous band Brass Rat, she's thrilled. Peter Gringras is so cool. When he plays his flute, it's as if he has some kind of hypnotic power. But there is something strange about him, something Callie can't quite put her finger on. Then, on Halloween night, Callie's little brother Nicky disappears, along with all the other children in town. It's crazy, but Callie thinks she knows where the children have gone—and who took them. To prove it, and to rescue Nicky and the other children, Callie must journey to a mythical world filled with fantastical creatures. A world from which there may be no return . . .
