Elbie throws his chest out. "We found you another ghost."

At the sound of the G-word, Kerry's eyes sparkle, and she gives Elbie a shove. "Get out. Where?"

"In our school library," he says, stumbling backward.

It's been a year since Theresa and her English friend, Kerry, won the Ghosters contest. Now her little brother, Joey, has stumbled on a mystery in the school library. Blasts of cold air, lights that flicker, and books flying off the shelves can only mean one thing. Ghosts. Joey's new friend, Elbie lives above his family's mortuary and is very comfortable around the ghosts that troop through its halls. He's also a prankster and doesn't mind Joey's quirkiness.

When books fly off the shelves at Joey and Elbie, they realize a spirit is sending a message through the books' titles. Then the ghost takes Joey's favorite book about bugs hostage, threatening to keep it until they help her. Always up for a spine-tingling adventure, Theresa and Kerry join the boys in their search for clues that will close a book on a decades-long, spirit-filled mystery.

Of course, nothing is easy for the Ghosters kids as they uncover more secrets and mysteries than a library full of books and nothing is ever what it seems.
