Looking for a book!

[Liza]

I really hope someone can help me. I read a recommondation from a book which is about a Girl and twins. The Girl is best friends (?) with one of the twin and the other twin is engaged but sexy as hell and an asshole (?).
I also read a Spoiler about this book, that the twins are one and the same Person at the end.
Story seems lame, thats why I didn't add it at my wishlist. Now I what to read it nevertheless and cannot find it anymore. Please, please help me.
