From what I can remember of the book there is an American girl called Blake. She moves to England for college(?) She has a boyfriend in America that she finds out has cheated on her. She has a group of friends in England. One of which she starts to date. He lost his parents and was brought up by his Grandfather who left his empire to him. Over the books they break up and get back together and in the end get married.
In one of the books (not sure which one) The group of friends go to a cabin for Christmas and the main guy brings his current girlfriend.
