Seven Sorcerers (Reprint)

Nin Redstone wakes up to discover that her brother has vanished--and she's the only one who remembers him. But when Bogeyman Skerridge comes for her, too, Nin realizes the true danger her brother, Toby, is in. To save him, she and her new friend Jonas must travel to a mysterious and magical land called the Drift. Located just next to our world, the Drift is being slowly destroyed by a terrible plague. The Seven Sorcerers who ruled there might have been able to prevent the devastation, but even they have succumbed. In a race to rescue Toby and get home before the plague makes it impossible, can Nin and Jonas avoid the tombfolk, mud men, and various creatures who want to stop them? And what is the secret of the Seven Sorcerers?
