WARP; The Forever Man
Riley, an orphan boy living in Victorian London, has achieved his dream of becoming a renowned magician, the Great Savano. He owes much of his success to Chevie, a seventeen-year-old FBI agent who traveled from the future in a time pod and helped him defeat his murderous master, Albert Garrick.
But it is difficult for Riley to enjoy his new life, for he has always believed in his heart of hearts that Garrick will someday, somehow, return to seek vengeance. Chevie has assured Riley on numerous occasions that Garrick was sucked into a temporal wormhole, never to emerge. The full nature of the wormhole has never been understood, however, and just as a human body will reject an unsuitable transplant, the wormhole eventually spat him out. By the time Garrick makes it back to Victorian London, he has been planning his revenge on Riley for half a century. But even the best-laid plans can go awry, and when the assassin decides to include Chevie in his retaliation, the three are tossed once more into the wormhole with no idea where—or when—they will end up.
