This is the best book to explore space with. It is an insiders look into a career and (out of) world that people don't get too close with usually. The way Kelley writes the book invites people into his life - from early childhood until today, through the trials and tribulations of the life of an astronaut. He simplifies the science enough that everyone can understand it, but can also see how challenging even 5 minutes on the ISS must be. He expertly weaves in stories of his childhood, his personal life, and his time at NASA. It is a page turner in the greatest sense, and despite knowing the end of the story, knowing how things work out, you are left on the edge of your seat. The beautiful color photos in the book also provide a personal look at space travel and the absolute beauty of this world. A highly recommended book for space lovers and non-space lovers alike.
