that summer

Hi guys! so i just finished reading my last Sarah Dessen book=[ Sunday was a sad day for me. It was a short book about a girl who is almost 6 feet tall at 15, her parents are divorced and she lives with her mom and sister who is getting married in less than a month. Her sister has had a ton of boyfriends in her time but one Haven the main girl still remebers is Sumner you learn it was her sister first love ans Haven first sense of what she believes a good guy is and she runs into him and he is kind of a crutch for her through out the book but never anything more than a friend, he reminds her of her favorite summer when her sister was dating him but suddenly they broke up and she blamed her sister (they dont have the best relationship throughout this book) but in the end you find out the first boy either one of them cared about was each there first disappointment.
