After writing an autobiography that sold millions of copies and earned him a hefty advance, former President Clinton has struck a deal to write another book.

Alfred A. Knopf will publish the new work, in which Clinton will focus on public service and citizen activism, telling a story that he hopes will "lift spirits" and "touch hearts," Clinton said in a statement.

The financial terms of the deal were not disclosed. Clinton is said to have received a staggering advance of $10 million to $12 million for writing "My Life," the 957-page memoir that Knopf published in 2004.

His inspiration for the second book, expected for release late next year or early 2008, was borne from the experiences he has had during his work and travel in the six years since he left the White House, Clinton said. It does not yet have a title.

Clinton plans to tell the stories of those he has met — and in some cases he will go back and interview them — to make the point that ordinary people can set forth change.

Clinton's path around the world has introduced him to tsunami aid organizations in Southeast Asia, doctors fighting to treat HIV/AIDS in Africa, neighborhoods trying to rebuild after Hurricane Katrina, and many more people that he believes are examples of what one person can do.

"We all have the capacity to do great things like this, and I am writing this book to encourage others to join their ranks," Clinton said. "My hope is that the people and stories in this book will lift spirits, touch hearts and demonstrate that citizen activism and service can be a powerful agent of change in the world."
