Abel's tale is told as a flashback, so we know from the beginning that there will not be a happy ending. Even knowing that, I was still shocked at the violent conclusion of Abel and Rima's story. Green Mansions is a novel of its time, in its unenlightened descriptions of the natives, who are portrayed as simpleminded, superstitious, and clever only when it comes to killing animals and being duplicitous. I also had to suppress my distaste for a grown man's (he's twenty-three) infatuation with a seventeen year old who is described as childlike. Ick. Consider yourself warned.
Green Mansions' plot has a pleasant tension that keeps you wondering what will happen next. I mostly enjoyed reading it, although at times I rolled my eyes at the sentimentality. Over the years, many editions were published, some with great pulp fiction covers, which I've shown below. It was also made into a movie starring Audrey Hepburn and Anthony Perkins. I suspect it may have been terrible, but what do I know?
