The book, "107 Days," will present a candid "behind-the-scenes account," Harris said. It's set for publication in September.

The memoir, titled “107 Days,” will be released on Sept. 23, and will give Harris’s inside account of her breakneck campaign for the White House after former President Joe Biden withdrew amid questions about his age and mental and physical fitness for office.

Jonathan Karp, the chief executive of Simon & Schuster, described Harris’ memoir as “not a typical political tome,” and continued, “It’s closer in spirit to ‘The West Wing’ or ‘Rocky.’ It reads like a suspense novel,” per The New York Times.
