Seven Sorcerers (Bk. 1)

Nin Redstone wakes up one Wednesday to discover that her little brother Toby, has vanished and non one - not her mother, not her grandparents - can remember him. Only Nin can, and she's going to get him back. But when Bogeyman Skerridge (who always gets his child) comes for Nin, too, she realizes that finding Toby is going to be a lot harder than she thought. With no other options, Nin heads into another land called the Drift with a boy named Jonas.
