I first read "Old Man and the Boy" about 50 years ago and have probably reread it, cover to cover, 10 times since then. I've enjoyed all of his books , but this is easily the best.
I haven't, but thank you for the thread, I just read up on the book and ordered a copy. Amazon.co.uk only had two left in stock, and its the only book I've seen with all reviews 5 star. Must be popular!
