Shade - Steven Gould

Steven Gould's classic SF novel Jumper is the story of a young man with a single mysterious superpower: he can teleport anywhere, in the blink of an eye. Now, in a story set after Jumper's sequel Reflex, we see that a single mysterious superpower can add up to a lot of different kinds of miracle...
In 2008 Jumper was brought to the screen as a big-budget SF adventure of the same name, directed by Doug Liman and starring Hayden Christiansen and Samuel L. Jackson. The movie rearranged the story line and gave the protagonist a teleporting sidekick. When the movie's producers expressed a desire to see a novel published about the sidekick's backstory, Gould chose to write the book himself; it was published as Jumper: Griffin's Story (2007), and is not canonical with the other two "Jumper" novels. "Shade" takes place in the world of the novels, not the alternate continuity of the movie.
