In-Roam

A crude, violent, and generally dislikable guy wakes finds himself in another universe with a device strapped to his arm that lets him jump through the portals that lead between its 500+ worlds. He wants answers, and he wants to know who brought him there. He's out to ruin everyone's day until he gets what he wants. CAUTION: strong language is used throughout the book, as well as a good deal of violence.
