Review: "The Astronaut Selection Test Book should corner the gift market much in the same way that GCHQ and Bletchley Park Brainteasers have done in the past couple of years." (Guardian); "Engrossing. a brain buster of a book. You'll learn plenty about space and what it takes to be an astronaut, but you'll also sharpen up your broader knowledge. For anyone interested in the space race and the imminent journey to Mars, here's the perfect stocking filler." (Starburst); "It's a brain work-out on steroids, stuffed with authentic selection tests. Entertaining and engaging. innovative, earnest, soulful and exhilarating" (BBC Sky at Night Magazine (Book of the Month));
