The memoir's title has not been released. But the website set up by Simon & Schuster, Hillaryclintonmemoir.com, gives readers options for ordering it from Barnes and Noble, Amazon, iTunes and other sites.
"Hillary Clinton shares candid reflections about key moments during her time as secretary of state as well as her thoughts about how to navigate the challenges of the 21st century," the blurb says.
Clinton, who became one of the leading members of President Obama's cabinet after losing the Democratic nomination to him in 2008, has not yet announced another run in 2016, saying she will make a decision by the end of the year. A book tour could be a chance to travel the country building support -- or it could be just a book tour.
While Clinton has joked about the book being "just a light summer read," she said in a speech Tuesday the memoir covers events like the bloody civil war in Syria.
