If you've ever been curious about space travel and all the work that goes into it, then you'll find this to be a well-written, interesting true story by a recently retired astronaut. Hadfield is at his best when he's describing the experience since it's as close as I'll ever come to space. The "life lessons" imparted throughout don't really strengthen the story and make it a bit preachy. I think he would've been better served if he'd simply focused on his bio without the take-aways. That said, it's still a great read. It made this week's launch of the Soyuz (and its delay in connecting with ISS) really come to life for me.
