Dana Reeve will reportedly write about living with her husband, who became an icon for the rights and causes of the disabled after a 1995 riding accident left him paralyzed from the neck down.
"It's the story of the changing landscape of their marriage and how their love deepened during their troubling times," a source familiar with the deal told MSNBC's "The Scoop."
"Dana is an amazing woman. She had worked with Chris's agent (Jennifer Rudolph Walsh at William Morris) and his editor (Ann Godoff at Penguin) and thought very highly of them both, so just made the deal with them."
The source said the book is tentatively set for a fall 2006 release.
