Alexa has setup her identical twin sister, Alissa, to go in to an arranged marriage with Russian oil tycoon, Sergei Antonovich. Alexa took the money and paid for their mother's home, as well as a few things for herself.
Alissa believes she is just taking a job to portray the bride for Sergei to comfort his elderly grandmother. She falls for Sergei, and finds him to be more than he first appears.
Sergei had not directly picked his bride, leaving it to the lawyers to follow his decree. Meeting her, Alissa does not fit in the box he thought she should. The more he learns about her, the more he wants to keep her.
Overal, a very good story, but I don't believe Alexa just changed in to a connieving bitch and scammed her sister suddenly.
