It's not easy to answer to Ed's post.

I haven't finished Scott and Leonov's "Two sides of the Moon".

The first one I've read was Collins' "Carrying the Fire" but that was years ago (it's still there, though).

I have enjoyed Cernan's "Last Man on the Moon" and would perhaps choose this one as the best. He took his time to write it!
I've also very recently read Cunningham's "The All American Boys" and it's a great book. But Walter, while being part of the Apollo program, didn't perform spacewalks nor went to the Moon.
All those books have different reasons for enjoying them and that's what makes them fascinating.
