Sarah Adams is a mother of two who lives in Nashville -- and "The Off Limits Rule" is her first book. It's also this week's book on Rick's Reading List. I'm not sure how I found the book, but I am glad I did. I needed a diversion from reading a lot of history and historic novels, and The Off Limits Rule did not disappoint. It's about a young woman Lucy with a 4-year-old boy named Levi, who breaks up with her boyfriend (not the little boy's dad) and moves home to live with her older brother. While there she meets a man named Cooper who happens to be her brother's best friend and former roommate.  It seems like a match made in heaven until her brother forbids her from dating his friend.  What follows is "the Off Limits Rule."
