This book is a gift to everyone who is a friend or has a friend - basically everyone. It is the beautifully-written story of two couples who remain close despite changes in physical location and life-altering situations. Wallace Stegner writes of each couple's unfailing courtesy toward and compassion for the other in truly memorable prose. The reader is able clearly to see each person individually, as part of a couple and as a member of their quartet. I truly hated to see this book end and I already look forward to reading it again and again.
