Is the book Return fiction?

You're likely asking about the book "The Return" by Hisham Matar. This book is non-fiction, specifically a memoir.

It's a deeply personal account of Matar's search for his father, Jaballa Matar, a Libyan dissident who disappeared in 1990 after being arrested by the Gaddafi regime. The book blends Matar's personal journey with a broader exploration of Libya under Gaddafi and the impact of political oppression.
