Old article, but GOLD article. When I started high school the SDHS library had a really nice science fiction selection that exposed me to really fantastic classic and obsure science fiction that was published from between the mid 40's to late 70's. This book (Dreamsnake) was one of them.

It is no longer in print but can be obtained online as the article states, and I recommd at least reading the original novelette "Of Mist, and Grass, and Sand" which as it turns out is also the first chapter of the novel. Though I believe it also stands quite well on it's own.
