Zero World

Technologically enhanced assassin Peter Caswell has been dispatched on a top-secret assignment unlike anything he's ever faced. A spaceship that vanished years ago has been found, along with the bodies of its murdered crew-save one. Peter's mission is to find the missing crew member, who fled through what appears to be a tear in the very fabric of space, emerging into an even more confounding reality: a world that appears to be Earth's twin.
