I should have loved this book, I am dead on the target audience for this. Same age, similar townie background, and in my ways I share some strong characteristics with Jo. However, this book fell flat in many ways. Let's pull a Jo and pro/con this:

Pros: 
-Realistic depiction of life in your mid 20s. Figuring out a career, where to live, who to love, etc. 
-The actual Throwback List was very fun and my favorite parts of the book were when the group would have to get together as a whole to complete one. 
-Funny! Lots of jokes and humor that I enjoyed. 

Cons:
-Massively underdeveloped characters. Jo and Bianca had the best development but it still wasn't great. Poor Autumn had nothing going for her. I couldn't connect with her as well because she wasn't a fully developed character. (I feel similarly about Flo and Birdy although they were side characters) 
-Jo's relationship with her parents was very underdeveloped too and the payoff for it was lame and not satisfactory. She was so horrible to her family and for what! 
-Jo's sexuality should have been touched on a bit more. Without spoiling anything, I was SOOOOO thrown off with one of the choices she made in the last couple of chapters. 
-Unsatisfying ending. It was very relastic but unless the author is planning a follow up book, kind of a let down.
