"Gravity" is a young adult novel written by Leanne Lieberman. It takes place in Canada, in and near Toronto and on the shores of Lake Missisagagon in 1987. It is told by the main character and protagonist, Ellie Gold, who recounts her experiences about discovering that she is gay and attempting to reconcile that with her desire to be an Orthodox Jew.

The novel begins when Ellie goes to visit Lake Missisagagon with her grandmother, Bubbie, for the summer. Ellie's parents, Ima and Abba, go to Israel for the summer, while Ellie's older sister, Neshama, attends camp. At Lake Missisagagon, Ellie meets a girl named Lindsay, to whom she is instantly sexually attracted. This sexual attraction over time becomes a romantic attraction. Ellie struggles to find common ground between her love of nature and being gay with her Orthodox Judaism. Things are complicated by the beliefs of other characters. Ellie's parents are devoutly religious; Neshama is a non-believer, and Bubbie is a casual believer.

Ellie ultimately goes through a crisis of faith. But after more research and good conversations with her mother, Ima, Ellie moves past her crisis. Ima tells Ellie that God is a force like love and gravity. He cannot be measured, but He is always present, even when other people get in the way. This helps Ellie's faith in Judaism return, and she finally finds a place of rest in her mind and heart where she can be both gay and an Orthodox Jew.
