This is a really sweet book. There is no love triangle here at all. 
 Nora is UNDECIDED about her major in college, not men. Actually, I don't really get why the book was named that either. 
 Nora has two extremes: a party girl and a bookworm. She isn't undecided about which one she wants to be, she is just trying to find a balance. 
 Cosbie is on the college track team and loves to party. But beneath the facade is a very sweet guy who loves performing magic tricks and works hard to excel at school. 
 These two have made mistakes in the past but they are both trying to fix them. This book had great banter and was pretty free of drama. Oh yeah, it was very romantic too :) I think it sends a pretty good message about making mistakes, paying for them and moving on with your life.
