  • "An engrossing, bubbly read, a boy's own adventure in scientific story-telling that fairly bounces along... a thumping good read"

  • "Sykes's wonderfully clear book should be compulsory reading for politicians... an eye-opening guide to the new branch of science that is changing the human race's view of itself"
