My friend found this cheap at a used bookstore and was inspired to re-read it. He convinced me to do so also, and I don’t regret it, though I think that I would have enjoyed it a lot more if I’d read it as a teenager. There’s a lot of ‘60s psychobabble that detracts from the basic ideas of the story, but there’s also a lot of real emotion to the story and the characters. I would definitely give it to a kid of the ages 11-16 or so.
