The Marriage Bargain is a great read, and one you won't want to put down!!  It takes you back to a first kiss between a young boy and girl, who had a spark from the start thanks to fate.  Fast forward to the same boy and girl as adults, and meeting again in a different situtation.  Both go into their "business-like" relationship with nothing more than making a deal, but come out with more than they expected.
