I was going to write about Wild Swans - fantastic fantastic read. Although I'm not sure it's strictly a biography?
I figure the depiction of her grandmother and mother's lives falls under biography and then the section on her own life is autobio.

I couldn't get into April Fool's Day- I don't think I like Courtney's writing style.

Also remembered:
Escape- life living in a polygamist sect
Bravo Two Zero- amazing story of an SAS guy being stranded behind enemy lines
