The Tin Drum is a novel by Günter Grass, considered one of the author's masterpieces and one of the key novels of the 20th century. The novel is the first book of Grass's Danzig Trilogy, and it tells the story of Oskar Matzerath, a boy who wills himself to stop growing and communicates through his tin drum. The book is a richly imaginative tale that combines history, folklore, and political commentary, presenting a surreal account of the rise of Nazism and the horrors of World War II.
