Grass is a powerful antiwar graphic novel, telling the life story of a Korean girl named Okseon Lee who was forced into sexual slavery for the Japanese Imperial Army during the Second World War—a disputed chapter in twentieth-century Asian history.

Beginning in Lee's childhood, Grass shows the lead-up to the war from a child's vulnerable perspective, detailing how one person experienced the Japanese occupation and the widespread suffering it entailed for ordinary Koreans. Keum Suk Gendry-Kim emphasizes Lee's strength in overcoming the many forms of adversity she experienced. Grass is painted in a black ink that flows with lavish details of the beautiful fields and farmland of Korea and uses heavy brushwork on the somber interiors of Lee's memories.

The cartoonist Gendry-Kim's interviews with Lee become an integral part of Grass, forming the heart and architecture of this powerful nonfiction graphic novel and offering a holistic view of how Lee's wartime suffering changed her. Grass is a landmark graphic novel that makes personal the desperate cost of war and the importance of peace.

Grass was published in English by Drawn & Quarterly on August 27, 2019, in French by Éditions Delcourt on September 26, 2018, and in Brazilian Portuguese by Pipoca & Nanquim on July 21, 2020.
