Query: A Middling Book by a Great Author

Babe Ruth was a great hitter. But he didn't connect with the ball everytime was was at bat.Farley Mowat is a great writer. Sadly not all his books are home runs. If you would like to read some of his best then try:-And No Birds Sang: The Farley Mowat Library-The Grey Seas Under: The Perilous Rescue Mission of a N.A. Salvage Tugor-The Boat Who Wouldn't FloatNot every book written by a great author is a good book - we all have our off days. But that should not stop you from reading his best work.
