Reconstructing Natalie by Laura Jensen Walker
A book about a woman who survives breast cancer and finds herself in the process. Also the Women of Faith Novel of the Year in 2006, I believe.
I've read it three or four times, and it only gets better.
Laura Jensen Walker's books are less "he's so cute" and more "I am woman!" But they're good books, usually pretty funny. And a lot of the time I can definitely relate.
