Billy Sure and the Haywire Hovercraft

Billy and Manny know exactly what Sure Things, Inc.’s Next Big Thing will be—a hovercraft! But when they start to build it, they notice it’s a little…haywire. The hovercraft dips, dives, twirls, and spins, until one day, it’s gone entirely, and so is Emily! Can Billy find his sister and fix the hovercraft, or will this be a crash landing for Sure Things, Inc.?
