NEW YORK (AP) - U.S. Sen. Elizabeth Warren, a favorite among liberals for her forceful advocacy for consumers and criticisms of the financial industry, has a book deal. The Massachusetts Democrat has an agreement with Henry Holt and Company for a book, currently untitled, to be released in spring 2014, the publisher announced Wednesday. Warren, a first-term senator elected last fall, will write about her childhood and early professional life, but the book will mostly be a "rousing call" for the middle class, according to Holt. She will describe her work on creating the Consumer Financial Protection Bureau and her opposition to powerful interests in Washington and on Wall Street. She will also provide an insider's view of Congress. "For decades, America's middle class has been chipped at, squeezed, and hammered," Warren, 63, said in a statement issued by Holt. I am eager to tell the story about my experiences on the frontlines of policymaking and to talk about what has happened to working families in this country and how we work together to rebuild the middle class. "Elizabeth Warren is a rare person in today's political world: a fiery advocate who believes that David can beat Goliath," said Holt's president and publisher, Stephen Rubin. Her core belief in the power of everyday citizens, along with her front row seat in Washington and her invaluable experiences as a teacher, lawyer, senator, wife and mother, show a devotion and fearlessness that will come though on every page of an elegant and informative book. Warren was well represented for her book. Negotiations were handled by Robert Barnett, the Washington attorney whose clients have ranged from President Barack Obama to former Treasury Secretaries Henry Paulson and Timothy Geithner.
