Summer is a novel by Edith Wharton published in 1917 by Charles Scribner's Sons. The story is one of only two novels to be set in New England by Wharton, who was best known for her portrayals of upper-class New York society. The novel details the sexual awakening of its protagonist, Charity Royall, and her cruel treatment by the father of her child, and shares many plot similarities with Wharton's better-known novel, Ethan Frome. Only moderately well received when originally published, Summer has had a resurgence in critical popularity since the 1960s.

Eighteen-year–old Charity Royall is bored with life in the small town of North Dormer. She is a librarian and ward of North Dormer’s premier citizen, Lawyer Royall. While working at the library, Charity meets visiting architect Lucius Harney.

When Harney’s cousin, Miss Hatchard, with whom he is boarding, leaves the village, Harney becomes Mr. Royall’s boarder, and Charity his companion while he explores buildings for a book on colonial houses he is preparing. Mr. Royall, who once tried to force his way into Charity's bedroom after his wife's death, and later asked her to marry him, notices their growing closeness. He tries to put a stop to it by telling Harney he can no longer accommodate him in his house. Harney makes it appear as though he has left town, but only moves to a nearby village and continues to communicate with Charity.
