Let the GHOUL times roll! Henry can't wait for his field trip to the French Quarter, New Orleans' oldest—and spookiest!—neighborhood. Not only will he and his best friend, Lily, find some cool facts for their local history project, they'll get to eat delicious beignets while they're at it. (Yum, y'all.) But inside historic Meredith Mansion, they find way more than they bargained for—including paintings that move, a possibly haunted music box, and one VERY grumpy ghost! Along with their friends, Henry and Lily will have to follow the creepy clues, explore mystical signs and symbols, and uncover an old family secret that someone may still be guarding, even from beyond the grave! And if they can't . . . it could be the last field trip any of them ever take.
