I first read this book fifteen or so years ago and even then it was old (it was first published before I was born, in 1965). I recently came across the book in a charity shop and thought I'd have another read as I remember it being an exciting and enjoyable story.
It was - and is - and I was glad to read it again. Like many books written decades ago, parts seem a bit old-fashioned, such as the portrayal of women (one character, whose name we know, is often referred to as `the girl'). I also found it interesting to read a book written at the height of anti-communist feeling as the story has a thread running through it of trying to thwart a group of communists who are trying to take over a South American country; the communists are portrayed like animals, not humans, and they are the worst thing that can happen. The European view of communism just doesn't feel like that now and the portrayal seems a bit over-the-top.
What's great about this story is the variety of characters and the situation in which they find themselves - stranded high up a mountain after a plane crash and threatened by an armed group of communists. The way in which the motley group of plane passengers arm themselves to fight back is brilliant, as is the description of a group of three making their way across a mountain pass in appalling weather and with hopeless kit. There's a lot of action and excitement in this story which is always gripping.
I did feel that the author was less successful in characterisation. We meet a variety of different people and they are convincing but the way in which they change isn't always so. There is a rather stereotypical ridiculous American chap and there are a few plot events which feel a bit too unlikely (the theft of a fighter jet, for example) but overall I really enjoyed this story and felt it was a little out of the ordinary compared to lots of action books.
