I have just finished Spaceman by Mike Massimino. I just want to say what a great book. It has so much to offer. If you are a tech nerd and like space related anything (you are, you are reading this) then what a great way to get an inside story from a contemporary astronaut. If you like an inspiring story then this is also highly recommended. This book should really find its way into the hands of young people. There are so many life lessons to be found. The two greatest: find and follow your passion and give up only after you have given it everything (everything means that you basically don't give up). He tells his story in a way that it is interesting and captivating to a wide audience. You don't have to be interested in space exploration or the space shuttle or techy nerdy stuff to enjoy or benefit from this book. BTW, I listened to the audiobook. He narrates himself and does an excellent job. You really feel his passion.
At the recommendation of TimB I have a copy of the Haynes Saturn V book (owners workshop manual). I have read it almost entirely through. I am someone that has come late to the game with little specific knowledge of the Apollo program (NASA and its program in general, to be more precise) and have found this book to be a great place to start. I have nothing to really compare it to but I feel like it is a great introduction with a lot of info.
At the recomendation of GordonD, TimB and Eric Mc, I have many books to look forward to. Thanks guys
