A memoir written by Alexei Navalny, a noted critic of Russian President Vladimir Putin who died in a Russian prison in February, will be published on Oct. 22.

The memoir, Patriot, will be published by Alfred A. Knopf and will print half a million copies, according to a report by the New York Times. Navalny started work on the memoir in 2020, and it will cover “his youth, his rise as a political activist, his marriage and family, his political career as an opposition leader, and the attempts on his life and attacks on those close to him,” according to the report.
