NEW YORK (AP) — The co-author of the million-selling “Game Change” has a book of his own coming about the 2020 election.

Simon & Schuster announced Monday that John Heilemann is working on a “dramatic, first-hand account” of Joe Biden's victorious campaigns over his Democratic Party rivals in the primaries and over President Donald Trump in the general election. Heilemann had collaborated with Mark Halperin on “Game Change,” about the 2008 race, and on “Double Down,” about 2012.

Halperin has since faced multiple allegations of sexual harassment. He was dropped by Showtime, where he and Heilemann hosted the political series “The Circus,” and a planned book by the two authors on the 2016 campaign was canceled by Penguin Press.

Heilemann's new book, currently untitled, draws on three decades of covering the former vice president, who was Barack Obama's running mate in 2008 and 2012. The publication date is not yet scheduled.

“I first met Joe Biden in 1986 when I was in college and he was getting ready to run for president the first time, and I’ve been following his ups and downs, his triumphs and tragedies, ever since,” Heilemann said in a statement. “The story of how, against all odds and against the apocalyptic backdrop of America in 2020, Biden rallied in the winter of his life to defeat Trump — and, in the eyes of many, to save the country — is one of the great political tales of this or any age, and I’m thrilled to have a chance to tell it.”

Screen rights have been acquired by Showtime, where Heilemann still hosts "The Circus." The HBO adaptation of "Game Change" won five Emmys and three Golden Globe awards.

Heilemann is national affairs analyst for NBC News and MSNBC and co-founder of the political video platform The Recount. He is also the author of “Pride Before the Fall: The Trials of Bill Gates and the End of the Microsoft Era,” which came out in 2001.

His current project adds to the list of books expected on the 2020 race, which includes works by Maggie Haberman of The New York Times and by Ryan Lizza of Politico and co-writer Olivia Nuzzi of New York magazine.
