The Black Moon Chronicles - Volume 7 - Of Winds, Jade, and Jet

As Baron Wismerhill, now lord and master of Moork and Horkher, becomes increasingly tied up in running his fiefdoms, he is invited by the emperor to join the priesthood of the Black Moon. But it's not that simple. First, he must pass the test of earth, fire, and water... a test that many don't survive.
