Bought for the Harem — Anne Herries

Thrown into a frightening and unfamiliar world after her capture by corsairs, Lady Harriet Sefton-Jones thinks help has arrived in the form of dashing Lord Kasim. But it's out of the frying pan and into the fire....

Kasim may once have been an English nobleman, but there is nothing noble about his intentions to purchase Harriet for his master the caliph's pleasure. Harriet must resign herself to a life of enslavement.

But Kasim has a plan of his own: charmed by Harriet's spirit and beauty, he's determined to claim her for himself!
