An inspirational, uplifting, and life-affirming memoir about passion, resilience and living life to the fullest, from Dr. Dave Williams, one of Canada’s most accomplished astronauts.

"I had dreamt about becoming an astronaut from the time I watched Alan Shepard launch on the first American sub-orbital flight on May 5, 1961. Eleven days before my seventh birthday, I committed to a new goal: one day, I would fly in outer space."
––Dr. Dave Williams
