This book is definitely sweet and fun, but what I like best is that there is actual substance to it! Like Gigi, Neerja, and Bea, I took AP and honors classes and participated in the nerdier aspects of high school, but thanks to the advice of my siblings before me, I also made sure to have a social life. This book is all about the girls finding out they need to create a life outside academia after a less-than-positive interaction with Neerja's Ivy-League-bound sister. 
 One of my favorite aspects of Smart Girls is the dynamic between Gigi and her female friends. The three main girls love each other so much so I was waiting for the typical screw-over-the-friend-for-the-boy, but it didn't really happen, which I LOVED. Gigi really knows how to put her friends first without going overboard. I also really enjoyed the dynamic between Gigi and Ava. Ava was hard to figure out at first, but then you realize she's just an insecure follower. 
 The boys: I'll admit, the first time Mike opened his mouth, I couldn't stand him. I have never though "aiii't" is an actual word, and it's especially not something you say when talking to teachers or people in a position of authority. But then I found Mike to be charming and adorable. Will....well, finally the new boy isn't all he's cracked up to be. 
 And does anybody else feel like Justin is (view spoiler)[totally crushing on Henry (hide spoiler)]?
