Henry Holt's Metropolitan Books imprint will publish This Fight Is Our Fight: The Battle to Save America's Middle Class, by Senator Elizabeth Warren (D., Mass.), on April 18, Holt president and publisher Stephen Rubin, who bought world rights, announced.

The book, which details, the publisher said, how Americans "can win the fight to revive and expand America’s struggling middle class," will be edited by Macmillan editor-at-large John Sterling. It is the second of the professor-turned-senior-senator's books to land at the imprint following 2014's A Fighting Chance. As with that book, Macmillan will simultaneously publish an audio edition of This Fight Is Our Fight, read by Sen. Warren.

“Elizabeth Warren is a fighter whose most potent weapon is her ability to communicate—to let the world know about wrongs that she seeks to right,” said Rubin. “Her personal experience growing up in a working-class family, her deep knowledge of American’s middle class, and the urgency of her message about the country’s trajectory make this book especially timely and important.”

Rubin acquired world rights from Robert Barnett of Williams & Connolly. A portion of the author’s proceeds from the book will be donated to the Greater Boston Food Bank, the Food Bank of Western Massachusetts, Worcester County Food Bank, and the Merrimack Valley Food Bank, the publisher said.
