Peter Caswell is a killer without a conscience as after every mission his mind is wiped and his guilt is expunged. When he is ordered into space at short notice and against protocol to investigate a missing spaceship that disappeared ages ago, all the safeties he had in his system are thrown by the side as he has to embark on a killing spree that will lead him to another, Earth-like, planet which sits at the other end of a wormhole. Here, in a medieval world centuries behind Earth’s technology he has to track down and kill a fugitive who could change the fate of not just the two planets but the whole universe. Saddled with an involuntary companion, Melni, a spy for one of the other world’s warring factions, he slowly begins to unravel a truth many would rather be kept silent. Non-stop action powers the plot along like a runaway train. ~ Maxim Jakubowski
In the near future, technologically enhanced superspy Peter Caswell is dispatched on a top-secret assignment unlike any he's ever faced. A spacecraft 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. Through this mysterious wormhole lies an even more confounding reality: a world that seems to be Earth's twin.
