"The Palleseen have sworn to bring Perfection and Correctness to an imperfect world. As their legions scour the world of superstition with the bright flame of reason, so they deliver a mountain of ragged, holed and scorched flesh to the field hospital tents just behind the frontline. Which is where Yasnic, one-time priest, healer and rebel, finds himself. Reprieved from the gallows ... he has been sequestered to a particularity unorthodox medical unit.
