I THOUGHT the title was Desert Prince or something along those lines but am getting no nibbles on Google. I can remember the book itself though not the character names:

So an American woman planned this great holiday with her friend and the friend ended up not being able to go. The woman still went to this middle east, desert country to spend time where she meet his sheikh and is escorted around by him. HE ends up being infertile with an ED problem due to a landmine way back when. They kind of hit it off, and he starts getting these stirring of feels he hasn't had in a LONG time. He explains to her that they can never "be" then beds her and is upset when he finds she is a virgin. Things till progress till the sheikhs old flame shows up with her son for a stay and the American ends up going home. Only to find out when she gets home that she is pregnant and predictably (but still I LIKE IT) he ends up coming from her, they confirm everything, do the mushy thing get married, his uncle like sets a bomb in the chapel or something ,is brought to justice the good guys win and they live happily ever after... SO anyone happen to know this book?
