Blood of the four / Christopher Golden and Tim Lebbon ; map by Eric Gunther.

"In the great kingdom of Quandis, everyone is a slave. Some are slaves to the gods. Most are slaves to everyone else. Blessed by the gods with lives of comfort and splendor, the royal elite routinely perform their duties, yet some chafe at their role. A young woman of stunning ambition, Princess Phela refuses to allow a few obstacles--including her mother the queen and her brother, the heir apparent--stand in the way of claiming ultimate power and glory for herself. Far below the royals are the Bajuman. Poor and oppressed, members of this wretched caste have but two paths out of servitude: the priesthood....or death. Because magic has been kept at bay in Quandis, royals and Bajuman have lived together in an uneasy peace for centuries. But Princess Phelas desire for power will disrupt the realms order, setting into motion a series of events that will end with her becoming a goddess in her own right... or ultimately destroying Quandis and all its inhabitants"--Amazon.com.
