I used to have lots of books by Piers Anthony. His playful, punful style and obvious love for the English language was something I enjoyed and found similar to my own writing style. However, I was bothered already then by his overuse of sexual innuendo: In his non-children books, the prose verged on pornography at times. This includes his "Cluster" science-fiction series to some extent, but the last book - Viscous Circle - has the saving grace of being about a species that is so fundamentally different from ours that even their love life is utterly alien. If you are bothered by "rubber forehead aliens" who are basically humans with some small variations, this book really stretches the imagination. At the same time it retains the belief in a fundamental common core, something like a mind or soul, common for all sentient beings. This belief, a complete immunity to xenophobia, I see as the main message of Piers Anthony's extensive writing through the decades.

This is going to mess up my recommendations, I guess, as I am not really into this kind of books now. But until I hit mid-life, I really liked it. If you want to give his adult books a try, this may well be the least offensive and most ethically encouraging of the lot.

Ronald Snowden is a Transfer specialist, one of those whose auras is over 50 times the baseline Solarian human level and can transfer their aura (mind, if you will) into another willing recipient. This time he is is to transfer onto the aura of a Band, a creature of rings that rides magnetic field lines and consumes energy directly from space. When Snowden crosses however, he finds that his host has not been willing and that his own aura has suffered amnesia to avoid any guilt this may cause. He now believes he is a Band named Rondl. A Band with strange memories and the previously unknown ability to perform aggression. For the Bands are almost Utopian in that they have no strife or conflict and help others immediately. Thought by Solarians to be animals it is clear to Rondl that they are sapient and would be easy targets for any aggressively territorial species. Like Solarians. Seeking an Ancient Site, a source of powerful technology, the Solarians are unwittingly (or wittingly) wiping out Bands. Rondl starts a resistance which is almost ineffectual, before he is whisked back to his own body. There he makes the realisation that he has gone native, and starts to undermine the Solarian efforts and actively plot to aid the Bands, one of which he loves. Piers Anthony closes his Cluster series with a fine tale of truly alien forms and mores. Despite his lengthy apologia at the end of the book it is a riveting and immersive story and only mildly sexist this time.

Overall a good classic Piers Anthony book. A little too much sexism. However, the authors note at the end was very meaningful to me. I found out some things about Piers Anthony that I did not know, which made me like him more.

Although the book suffers from the blatant sexism of its day, it was forward thinking for its time, and had some very positive messages about what ideals should be truly valued. The science in the book was hit or miss; some parts make it seem like hard science fiction, but other parts are so implausible on their face that it made me wonder why the author attempted to be so scientifically accurate in the more rigorous sections. Apparently, the author wrote this book while going through a serious illness, so that might explain some of the defects. Nevertheless, it was a fun read, and I don't regret going through it, flaw-filled though it may have been.

this book was okay, The character design was great and it was cool and actin packed, but it seemed so tired. This might have something to do with the fact that Piers was suffering from cat scratch fever at the time. Also is this his first author's note, cause that would be pretty interesting.

The last in a series of five, this was a nice way to cap it off. Delved into a lot of ethical issues, which I enjoy. Also had a great Author's Note at the end. Love Piers!

I liked all the cluster books, but was surprisingly bored and more often then not having to force myself to finish, sad that's how the collection ended.
