Facts are the closest things Sam has to a friend but they're no use when ghosts start talking to him. He's determined to find answers to problems, but when he sees crazy twisting vines and ghostly faces at an abandoned house he's thrown out of his element. Then there's the folktale about the Dragonfly, which sank nearly 200 years ago and has yet to be found. Could the ghosts he's heard be the key to finding the ship-and her treasure? Sam needs help, but are the kids from the campground really his friends? Will they help him when an unnatural storm takes them further than they ever imagined? Or will Sam be on his own to solve the mysteries before they run out of time?
