Set in the Middle Ages during the rule of the Norman kings, The Ruby in Her Navel is a tale in which the conflicts of the past portend the present. The novel opens in Palermo, in which Latin and Greek, Arab and Jew live together in precarious harmony. Thurstan Beauchamp, the Christian son of a Norman knight, works for Yusuf, a Muslim Arab, in the palace’s central finance office, a job which includes the management of blackmail and bribes, and the gathering of secret information for the king. But the peace and prosperity of the kingdom is being threatened. Known for his loyalty but divided between the ideals of chivalry and the harsh political realities of his tumultuous times, Thurstan is dispatched to uncover the conspiracies brewing against his king. His journeys send him on a spiritual odyssey that forces him to question the nature of his ambition and the folly of uncritical reverence for authority.
