"A fun haunted house story full of mystery and heart!"--Lindsay Currie, #1 New York Times bestselling author of The Mystery of Locked Rooms

After twelve-year-old Charlie moves from New York City to sweaty, sticky Florida, she'll do anything to get back home.

Even if it involves ghosts.

Winklevoss Manor, Charlie's new house, is a towering Victorian mansion famous for one thing--it's haunted. Three ghosts--Ada, Arthur, and Guff--live there, and not by choice. They're trapped, cursed for stealing a dead man's diamond. A diamond that, just like the ghosts, is still in the house. And this gets Charlie thinking. . .

Maybe if she can find the diamond and sell it, Charlie's family could have enough money to move back to the city. But lifting the curse isn't that simple, especially when she's pitted against the school bully and three unruly spirits. It's frightening to think about, but what if the only way to get rid of the ghosts and curses is by doing what Charlie fears the most--confronting the past that haunts her?
