the Queen's Pawn by Christy English recounts the life of Princess Alais of France, who was destined to marry Richard, one of Henry II and Eleanore of Aquitaine's offspring. I have read so historical fiction novels that graze over Alais, other than to mention she was left to languish in England for several years waiting to marry Richard and, eventually, caught the eye of the adulterous Henry.
I hope to learn much more about Alais and her life in the Queen's Pawn. Welcomed by Eleanor as a daughter, the relationship sours when Henry begins to view Alais with typical undisguised desire. Now Alais is Eleanor's rival, a battle the strong-willed Eleanor is determined to win.
