I have read every single book that Carrie Fisher has written.
She cracks me up.
Her memoirs are raw and funny. Her fiction is like reading a memoir that makes you laugh and cry together.
As for Augusten Burroughs: to me, he is like a male parallel to Carrie. His memoirs are so outrageous you would think they are fictitious!
They both write with brutal honesty, and from this, the reader gets the humor and the pain.
