Fearless on Everest: The Quest for Sandy Irvine, (Mountaineers, 2000; $18.95.) tells more about Sandy Irvine than has ever been told before. Written by an admiring relative, Julie Summers (his sister’s granddaughter), it is by no means a disinterested treatment. Nor is it the work of a professional historian or biographer. But anyone captivated by the 1924 British Everest expedition will be thankful Ms. Summers decided to ferret out this long forgotten information.
