I was looking on Elizabeth Scott's blog and I saw some things about her upcoming novel The Unwritten Rule. Here is the cover:
This was the little tidbit about the book:
The Unwritten Rule is a story about a girl, Sarah, who falls for her best friend's boyfriend. As you can probably guess, things get really complicated really fast and The Unwritten Rule is about friendship and family and love and the agony of breaking that unwritten rule about falling for your friends' boyfriends (especially you best friend's boyfriend!) (and of course, now you know how I got the title too!)
It's supposed to be coming out April of next year. So keep a look out for that.
