The Prince's Heir

Read the gripping conclusion to The Five Kingdoms...
King Marten's reign teeters on a blade's edge. Chel's Casket, symbol of his right to rule, is missing. Can master spies Rustam and Risada recover it before someone notices its absence and challenges Marten's sovereignty? Or is there a more sinister motive behind the disappearance of the casket—a relic that could be used to raise Charin, the demonic half of the dual-natured divinity?
As a series of natural disasters besets the kingdoms, evidence points towards interference by the meddlesome deity, and the terrifying prospect of war between its two opposing aspects. 
When Marten's beloved wife, Betha, and their infant daughter vanish, Marten faces a stark choice: save his family, or try to save his kingdom from a conflict that threatens all humanity.
