That Summer is a 1996 young adult novel by Sarah Dessen.
The story follows fifteen-year-old Haven McPhail over the course of one change-filled summer, as she struggles to adjust to a new normal— her father is getting married to the woman he left her mother for, and her older sister Ashley is planning her wedding and preparing to move on with her life. It's all too much, and when she starts a friendship with Sumner, one of Ashley's ex-boyfriends, Haven starts to reminisce about the summers of her childhood, when nothing was complicated and everything was happy...
Along with Dessen's next novel, Someone Like You, it was adapted into the film How to Deal.
