I went into this thinking it was going to be your cliche young adult love story. Don't get me wrong it had the typical young adult contemporary necessities; a love triangle, a young girl making mistakes, and eventually learning from those mistakes. I really love how it took on the importance of family and sisterhood though. As an only child raised in a single father home I never really got to personally experience some of the things mentioned and it was interesting reading about them. 
 We have Lara Jean as our main character being the middle daughter, Margot the oldest and "wisest", and Kitty being the youngest and most feisty. When Margot goes away for college in Scotland Lara Jean is thrown into the role her sister played and takes care of her family as well as herself. It was a great family dynamic and played such an important role in the book. 
 Lara Jean has been writing love letters to boys her entire life. It's her way of letting go and moving forward from a relationship that never truly existed. Then one day all her letters she's been keeping go missing and boys from her past and present are receiving them in the mail. One by one she learns to deal with them all and how to truly move forward and find love. 
 (view spoiler)[I'm all for #teampete as long as he gets away from that bitch Gen. I would love to know why Pete is always standing by Gens side though and what dirty laundry she's hiding. 
 Josh is just way too problematic with being her sisters first and everything....awkward and uncomfortable. I thought for the longest time Gogo sent out the letters herself and that's why she broke up with Josh before leaving for school! I thought she realized how much her younger sister cared about him but nope.... (hide spoiler)]
