Young FBI agent Chevie Savano arrives back in modern-day London after a time-trip to the Victorian age, to find the present very different from the one she left. Europe is being run by a Facsist movement known as the Boxites, who control their territory through intimidation and terror.

Chevie’s memories come back to her in fragments, and just as she is learning about the WARP program from Professor Charles Smart, inventor of the time machine, he is killed by secret service police. Now they are after Chevie, too, but she escapes–into the past. She finds Riley, who is being pursued by futuristic soldiers, and saves him. Working together again, it is up to Chevie and Riley to find the enigmatic Colonel Clayton Box, who is intent on escalating his power, and stop him before he can launch missiles at the capitals of Europe.

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.
