That Summer is Sarah Dessen's first novel, published in 1996.

[1] This novel and Dessen's Someone Like You are the basis for the film How to Deal.

[2] That Summer tells the story of a 15-year-old girl Haven, as she copes with her sister's engagement, her father's remarriage, and her best friend's personality changes.

Nothing seems stable except for Haven's memories—especially those of the summer when Ashley dated Sumner Lee, who, as part of the backstory, is described as bringing the family together.
