Rowan Creed, a teenage boy with a passion for adventure, longs for a treasure hunt in a world that seems devoid of real excitement. After discovering a second-hand metal detector at a garage sale, he dedicates his summer to searching for hidden treasures along the beaches of Ashmere. After an unsuccessful day combing the familiar shores for relics, Rowan decides to venture deeper into the wilderness, leading him to a secluded beach untouched by modern explorers. It is here that Rowan uncovers a mysterious silver coin that unlocks a series of magical events. This coin, once transformed into a locket, grants him the ability to see hidden magical wonders around him and ultimately leads him to a ship trapped within a bottle in an ancient cave. Unbeknownst to him, this ship is a gateway between worlds, and when he releases it, Rowan is transported to an abandoned island.
