Flinx's Folly — Alan Dean Foster

It's a good thing Flinx is no stranger to trouble, because he's swimming in it. After surviving an attack by a new gang of assailants, Flinx is spirited away and enlisted in a battle against an extra-galactic threat. Hidden behind the Great Emptiness, in a place where it seems matter and energy have never been, there is only evil. Pure evil that is approaching him, accelerating.

This terrifying, high-stakes adventure through perilous new realms will rocket Flinx into the very heart of danger--and into the arms of the only woman he's ever loved. As he and Pip bravely travel to a place where no man or mini-drag has gone before, Flinx discovers he has a few more friends than he thought--and far more enemies than he ever imagined.
