Not even the Church of the Invincible Sun is invincible - and somebody has to do its dirty work. Enter Sister Svangerd and her accompanying priest, both first-rate practitioners. Their mission is simple: to make a meddlesome princess disappear (permanently). To get to her, they must attend the legendary Ecumenical Council, the once-in-a-century convening of the greatest spiritual minds the world has to offer. But when they arrive, they find instead a den of villainy that would make the most hardened criminal blush. To complicate matters further, it appears that some people who were definitely grim reapered might be not quite dead after all. What began as a little assassination is about to escalate into a theological debate with terrifying consequences for everyone.
