Banners of Gold — Pamela Kaufman

The enchanting Alix of Wanthwaite returns in a suspenseful and richly textured adventure in which nothing less than the future of England is at stake.

Alix is home at her beloved estate on the Scottish border when King Richard's soldiers march into her castle and demand to take her to the Continent with them. King Richard has been captured while on Crusade, and Alix is among the nobles whose lives will be collateral for the king's ransom. But when she's delivered to Queen Eleanor of Aquitaine, Richard's mother, she is dumbfounded to learn that the queen has other plans for her.
King Richard needs an heir, Eleanor tells Alix. Repulsed by his queen, a homely religious fanatic, he has told his mother that the only woman he wants is the one he met on Crusade, when she was disguised as a boy. Richard wants Alix to be his mistress and the mother of the next Plantagenet king. Now a beguiling and irrepressible young woman, Alix faces more tribulations -- and romance -- on this trip to Europe, where affairs of the state and affairs of the heart are intricately intertwined.
