 There s been a prison break. Two hundred and eighteen dangerous convicts have escaped. They re led by Zin, the smartest and most ruthless felon known to man. But these criminals aren t from any world we know - they re from planets that could eat us for lunch. Zin devised a wormhole in space that transported all of them to Chicago, where they ve set up shop and now traffic in every kind of criminal activity imaginable. We are virtually defenseless against their extraordinary powers: the ability to take the form of any human or animal, super-strength and speed, superior intelligence, and something even more frightening - each one of them is a different kind of alien being - and they each have powers that are individual, unique - and immense! But the prison has sent help. A Tracker. His mission is to capture each and every one of them, dead or alive. He teams up with Mel, a hard luck girl who is finally on the road to salvation. Mel is the owner of a Chicago pub, The Watchfire, located downstairs from the Tracker s base of operations. The Tracker and Mel are a kick-ass couple, an alien and an earthling. Fighting the evils of the universe - and, at the same time fighting something even stronger - an attraction to each other.
