I didn't include Caitlin Moran in the earlier post on funny women writers because although she is a bit of a celebrity, she's a journalist and writer first and foremost. I just finished her amazing pseudo-memoir How to Be a Woman in which dispenses sage wisdom based on her extremely hilarious and often crass personal anecdotes (In response to being called "Fatso" as a teen: "I'm fat because every time I fuck your dad he gives me a biscuit"). It's fairly filthy but really funny and very endearing and sweet, a bit like if Georgia Nicholson grew up to write a book on feminism and growing up. I especially love the image of her on the cover; she could be a hip witch character from Harry Potter.
Her new book How to Build a Girl is a coming-of-age novel that seems largely autobiographical. The heroine Johanna grows up in a very bohemian family and becomes a music writer at 16, much like Moran herself. I haven't read it yet because I'm on a very long wait list at the Public library for a copy, but I can't wait to just devour it.
