The Last Crusader Kingdom — Helena P. Schrader

John d'Ibelin, son of the legendary Balian, will one day defy the most powerful monarch on earth. But first he must survive his apprenticeship as squire to a man determined to build a kingdom on an island ravaged by rebellion. The Greek insurgents have already driven the Knights Templar from the island, and now stand poised to destroy Richard the Lionheart's legacy to the Holy Land: a crusader foothold on the island of Cyprus.
