3.5 stars, rounded up. 
 Well, this was fun - in a slightly cheesy 1970s way :-) 
 Dreamsnake is set in a future post-apocalyptic landscape, but it reads more like fantasy. It was more hopeful and upbeat than most such tales, and I enjoyed that about it. I like snakes, and I liked that they were used in healing work in this story. And the key to breading the "dreamsnakes" was fascinating and delightful. I really couldn't buy the romance aspect of the story, though, it just felt too contrived. 
 I listened to the audiobook of this - the narrator was OK, but definitely needed speeding up!
