Hawking's Hallway (The Accelerati Trilogy, Bk. 3)

Nick Slate, in order to protect his father and little brother, reluctantly must help the Accelerati complete Tesla's great device. Their power-mad leader wants nothing less than to control the world's energy--but there are still three missing objects to track down.

Nick's friends can't help him, as they are spread across the globe grappling with their own mysteries--with Vince in Scotland, Caitlin and Mitch on their way to New Jersey, and Petula's whereabouts unknown. On his own, Nick must locate Tesla's final inventions--which are the most powerful of all, capable of shattering time and collapsing space.
