Critically acclaimed author Kimberley Griffiths Little spins a thrilling story of one girl's race to unravel the curse that has haunted her family for generations. When Larissa Renaud starts receiving eerie phone calls on a disconnected old phone in her family's antique shop, she knows she's in for a strange summer. A series of clues leads her to the muddy river banks, where clouds of fireflies dance among the cypress knees and cattails each evening at twilight. The fireflies are beautiful and mysterious, and they take her on a magical journey through time, where Larissa learns secrets about her family's tragic past — deadly, curse-ridden secrets that could harm the future of her family as she knows it. It soon becomes clear that it is up to Larissa to prevent history from repeating itself and a fatal tragedy from striking the people she loves. With her signature lyricism, Kimberley Griffiths Little weaves a thrilling tale filled with family secrets, haunting mystery, and dangerous adventure.
