Hawking's hallway: Book 3 of the Accelerati trilogy

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.
