From the description:
"When legendary killer Ciris Sarn ends a life in an empty city plaza with a single dagger thrust, little does he know that an insidious game has been triggered by the brutal slaying. Turning predator into prey, this part fantasy, part espionage novel races along as it follows the now hunted Sarn across the brilliant white sands and sparkling seas of Mir'aj, pursued by the widow of his latest victim who will stop at nothing for vengeance."
