Book excerpt: Eleven-year-old Orion lives with his stodgy grandfather in eastern Maine, where nothing exciting ever happens. But then a series of strange events draws him into the mystery of a lost explorer, and Orion is swept up in a whirlwind of adventure that takes him to the top of the world. To survive he must outwit a scheming treasure hunter, team up with a gang of flimps, and take on a tyrant with an anger management problem. Can Orion solve the mystery and get back home alive? And just what are flimps, anyway? Orion Poe is about to find out. Join him as he laughs, cries, bluffs, and shoots his way to the heart of one of the greatest mysteries in the history of exploration. Along the way he discovers that the world is far bigger—and stranger—than he ever imagined.
