The second book in the DRIVE series, "The Emperor Calls" picks up right in the middle of the action: The crew of the Machito, having been press-ganged into a secret mission, seeks out pilots for humanity's fight against the "Continuum of Makers". Meanwhile, a rogue Maker rebels against his own people toward an uncertain end. And the new emperor recalls the entire ruling family to earth -- halting humanity's preparations right on the cusp of war. Hooo doggy, the action is heatin' up, my friends. Heatin' up!
