Previously published as The Smoky Corridor.From theNew York Timesbestselling author ofEscape From Mr. Lemoncello’s Libraryand coauthor ofI FunnyandTreasure Hunters, comes a series of spine-tingling mysteries to keep you up long after the lights go out.

Where there’s smoke, there’s fire. It just doesn’t usually come from the grave.

The basement of Zack’s new school is hiding something, or rather someones. Two ghosts, to be exact-Joseph and Seth Donnelly, brothers who perished in a suspicious fire.

But the ghosts are the least of Zack’s problems. It’s what they warn Zack about that has him truly frightened- there’s an evil zombie lurking beneath the school.

Fortunately, Zack has some new friends, Malik and Azalea, who can help in his paranormal adventures. Together they’ll attempt to dodge the zombie, a treasure-seeking hit man, a voodoo-savvy ghost just waiting fora new body, and more. But will they survive until recess or end up on the lunch menu?
