I read a book a few years back. It's a YA duology where the cover is a girl holding a knife behind her back. The plot covers how the girl's father and the boy's father were once friends but due to some problem got divided into two groups ,them being the leaders. The girl's family lives on the non-wealthy side and the boy's family on the wealthy side. The girl is selected to marry the boy instead of her sister n was trained by her sister and father to murder him. After marrying him, she realizes that the boy is a good person and starts to slowly fall in love with him.
