Return to Shadow School for the second installment of the spooky middle-grade series from J. A. White, the acclaimed author of Nightbooks and The Thickety series. Now available in paperback.

Cordelia Liu's first year at Shadow School was a success. She studied hard and made friends. She also sent hundreds of ghosts into the afterlife, because Shadow School isn't a normal school, and Cordelia Liu isn't a normal girl.

But her second year is already different. Ghosts are refusing to move on, the teachers are acting weird, and Cordelia's best friends, Benji and Agnes, aren't as interested in rescuing the ghosts as they used to be. Benji is busy hanging out with the girl he befriended over the summer, while Agnes spends all her time building a machine that might be capable of dehaunting the school forever.

Cordelia is the only one who believes that something sinister is happening right under their noses. But what if it's even worse than she could imagine?
