This thorough recounting of the first manned trip to the moon is riveting in parts and educational throughout. The complexity and enormity of the undertaking are only appreciated after reading this book. The mission was an extremely daring choice by NASA since the Atlas rocket was not a proven vehicle and the training schedule had to be greatly rushed. The biographies of the three astronauts are set forth with the right amount of detail, enough for us to get to know them and their families as people but with the focus kept on the voyage to the moon. The author tends to be quite repetitive, thus causing me to drop a star on the rating. How many times to we need to be told that if step X goes wrong the astronauts could end up crashing into the moon, flying off into space or trapped in a lunar orbit indefinitely? He does it about three or four times every chapter. Still, it was an enjoyable read.
