Surviving and making his way back will be hard enough, but, unbeknownst to Tom, there is also a grim conspiracy of treasure hunters at work to make sure he doesn't come back.
Wilson always does a nice job of presenting positive--albeit quirky--characters in a story with real stakes. He doesn't shy away from peril and darkness, but he always balances it with light and redemption. A good choice for adventurous kids whose parents don't want anything too mature. (As a bonus, classics fans will get a kick out of elements from The Odyssey, Tom Sawyer, and other famous works, which Wilson nods to without following slavishly.)
