NEW YORK - Former Secretary of State Condoleezza Rice is working on a book about democracy.

Henry Holt and Company announced Tuesday that the book, currently untitled, will be published in 2015. The 58-year-old Rice has previously written or co-written a handful of policy books, along with memoirs about her family and her years in the George W. Bush administration.

She served as national security adviser during Bush's first term and secretary of state during his second term. She is currently a professor of political economy and political science at Stanford University, where she has taught off and on since the early 1980s.

In her new book, Rice will draw upon personal and professional experiences to address such issues as self-government, immigration and education.
