Thomas Hammond has always lived next to Leepike Ridge, but he never imagined he might end up lost beneath it! The night Tom”s schoolteacher comes to dinner and asks Tom”s mother to marry him, Tom slips out of the house and escapes down a nearby stream on a floating slab of packing foam. Eleven-year-old Thomas is in for the ride of his life as he's swept downstream and underground aboard the crumbling raft of Styrofoam. Washing up on a dark subterranean "beach," his only companions are an impulsive dog named Argus and a corpse, from which he takes a flashlight and an all-too-limited supply of batteries. What Tom finds under Leepike Ridge — a castaway, four graves, a tomb, and buried treasure — will answer questions he hadn't known to ask and change his life forever. While his widowed mother continues to search for him, Tom, presumed dead after drifting down a river, finds himself trapped in a series of underground caves with another survivor, and pursued by murderous treasure-hunters. Now, if he can only find his way home again. . . . An original mix of "Robinson Crusoe, King Solomon's Mines, The Adventures of Tom Sawyer, "and "The Odyssey," N. D. Wilson's first book for young readers is a remarkable adventure, a journey though the dark of the grave and back out into the light.
