I enjoyed this one a lot. It's perfect for someone who's in the mood for an easy going contemporary (which I was). The biggest themes this book had was family and relationships. Lara Jean lives with her dad, her only living parent, and her two sisters. I liked how close she was to her sisters. And I thought her little sister Kitty was the cutest. 
 This book surprised me because I thought it would be more of a mystery. More of Lara trying to figure out who sent out her letters. But it was nothing like that. She didn't even try to figure that out. It was more of her just dealing with it, which was okay, I was just caught off guard with that. But I would say this book is less of a mystery and more of a romance. 
 This was a four star for me because I just couldn't stand Lara's whining sometimes. She's a 12 year old trapped in a 16 year old's body. And the way she dealt with problems she faced was so immature. She was always crying and whining when people thought badly of her which I thought was stupid and unnecessary because it's not even a big deal. (*cough* drama queen) 
 I still liked it nonetheless and I would recommend it if you can get past Lara's dramatic episodes. I will be reading the sequel soon. :)
