The books will be published at a time when John Edwards is traveling around the country testing the waters for a 2008 presidential bid. Elizabeth Edwards' book proposal is being circulated to publishers by Robert Barnett, a Washington lawyer who helped her husband land a book deal. Barnett said he is finding "enormous interest."

John Edwards wrote an autobiographical book, focusing on his law career, called Four Trials, while he was seeking the Democratic nomination for president in 2004.
