Norah Lofts 
Concubine 

Black-haired, black-eyed, she had a wild-sprite quality that was to prove more effective, more dangerous than conventional feminine appeal. The king first noticed her when she was sixteen — and with imperial greed he smashed her youthful love affair with Harry Percy and began the process of royal seduction. But this was no ordinary woman, no maid-in-waiting to be possessed and discarded by a king. Against his will, his own common sense, Henry found himself bewitched — enthralled by the young girl who was to be known as — the Concubine.
