Which Malcolm X biography should I read?

Malcolm X's autobiography is the only authentic one I know of. It is called "The Autobiography of Malcolm X" but it was actually written by Alex Haley (the writer of "Roots"), who wrote the autobio based on a series of conversations Haley had with Malcolm X shortly before his ination. There are a few inaccuracies in the book, but it was edited and approved by Malcolm X himself and there is no other account of Malcolm's life that comes close to being recognized as his true autobiography.
