My family bought me this book for my birthday at least partly to see whether reading it might make tea come out of my nose as had gratifyingly (for them) happened with an earlier Bill Bryson book that I had anti-socially taken to the table because I couldn't stop reading it.
It didn't, but it did cause me to go AWOL from my domestic responsibilities for quite some time, and sometimes to stagger round clutching my head as my brain refused to assimilate any more. I enjoyed it enormously. It's Bill Bryson's enviable gift to be able to write so clearly and elegantly, conveying his enthusiasm without drawing attention to his erudition. The fact that you find yourself becoming passionately interested in glaciers after a lifetime of not giving them a second thought says it all. Reading this book is a moving, frightening, awe inspiring and yet curiously optimistic experience, and everyone should do it.
My only complaint is that Doubleday have chosen not to bind this book properly. Gluing books together, especially hardback books, ought to be some sort of crime.
