This Mary Poppins, She Wrote is one of the best bios I've ever read.
A more detailed review later. But this is why you can't trust group averages. If I can find a bookseller with as reliable a mail service, I might transfer to a different one. Maybe the actual publisher.
If two people rate a book 4 stars and one rates it 3.5, thats two people rating 4 stars and one 3.5. Not an average of 3.75.
