Innocent Mistress, Royal Wife by Robyn Donald
Mistress - by royal appointment!
Prince Rafiq de Couteveille believes Alexa Considine to be a money-hungry mistress, and using her to avenge his sister's death will be sheer pleasure... Lexie can't understand why she's attracted the attention of the Crown Prince of Moraze - she just wants a quiet holiday.
But Rafiq is hard to resist, and soon Lexie finds herself bedded by royalty. But to Rafiq's horror and shame Lexie is a virgin! Out of duty and honour, he must propose!
