Hi Everyone! I am looking for the TITLE/AUTHOR of a sweet historical romance novel that I read awhile ago. It was about a blonde girl who had been kidnapped and given to a sheik's son as a second wife. She escapes and returns to her British family where her childhood friend (a Duke?) who used to find her when she got lost. He helps her get accepted back into Society. He falls in love with her again and they marry.
