WARNING: ADVENTURES IN LIBRARIES ARE CLOSER THAN THEY APPEAR. At least that's what Landon discovers when a few drips from a library ceiling turn into a powerful waterfall. As the waters rise, so do the perils in this latest adventure of Landon Snow, as he and his sisters - Holly and Bridget-are transported out of the library and into another world. In this high-seas voyage, the Snow children join a quest to find the Island of Arcanum, where the animals of Wonderwood are imprisoned and the evil shadows of Malus Quidam lurk. With the help of some old friends-a horse named Melech, an odd fellow named Hardy, a girl named Ditty, and the poet/prophet Vates-Landon seeks to unlock the island's dark secrets and escape with the animals intact. But first he must navigate his way through uncharted waters and battle the villainous Arcans. Can Landon and his friends rescue the animals from deep within the island's stronghold? Are the winds in Landon's favor, or will this prove to be his final voyage?
