"Toby's Room" is a novel written by Pat Barker, published in 2012. It is the second book in the "Regeneration Trilogy," following "Regeneration" and preceding "The Ghost Road." Set during World War I, like the other books in the series, "Toby's Room" delves into the psychological effects of war on soldiers and those around them. The story revolves around siblings Elinor and Toby Brooke. Toby is a talented artist who joins the army during World War I, while Elinor is studying at the Slade School of Fine Art. When Toby goes missing in action, Elinor is determined to find out what happened to him, and she delves into the complex and often disturbing world of military hospitals, where soldiers are treated for physical and psychological wounds. The novel explores themes of grief, trauma, and the search for truth amidst the chaos of war. It also examines the role of art in processing trauma and the ways in which war can shape individuals and their relationships. Like Barker's other works, "Toby's Room" is praised for its vivid depiction of wartime Britain and its nuanced exploration of the human psyche. It offers a compelling portrait of a family grappling with loss and the lingering effects of war.
