Previously published as The Hanging Hill. From the New York Times bestselling author of Escape From Mr. Lemoncello's Library and coauthor of I Funny and Treasure Hunters, comes a series of spine-tingling mysteries to keep you up long after the lights go out.

Every theater has its demons.

At this one? They’re real.

Zack is staying at the Hanging Hill summer theater, a place where he and his family hope to recover from the fiery fallout of Zack’s last ghostly encounter. The theater is all set to stage Zack’s stepmother’s play . . . or so they think.

What Zack doesn’t know is that the director has another show in mind, and that production requires a child born under a full moon. A child who will not survive opening night. And Zack? He was born under a full moon.

Zack has battled evil spirits before, but this time he’ll learn that just because it’s a playhouse doesn’t mean that the ghosts are playing.
