Deadfall — Gary Russell

Jason Kane, Benny's useless ex-husband, finds himself trapped on the legendary planet Ardethe. Activating the distress beacon he stole, he summons Chris Cwej, who promptly has his mind wiped by the machinery he inadvertently awakens. A prison ship then arrives full of women convicts and suddenly people start dying. Jason doesn't know who the true foe is and Chris doesn't even know his name.
