This 5 book series written in the late 1970s was my favorite by far when I was in high school. Re-reading it today though, Jack Chalker's style is inconsistent at best, almost amateurish in places. But I love this universe and I love these characters. It's the ideas that have carried me through this and have never left my mind all these decades. The will of souls, also known as the Will World, is a gigantic planet at the center of the universe that is actually a tremendous computer that generates the mathematics that maintain reality. The surface of the planet is inhabited by thousands of sentient races, each with their own habitat and ecosystem. Half of them are organic and carbon-based like us. The other half are not. The planet also served as a laboratory for an ancient race of godlike beings who appear to have gone extinct not long after activating the Will. It's a plot idea that's designed to give the author free reign to create every crazy kind of being in situation that he can imagine. In some places, Chalker is brilliantly creative and in other places he just isn't. Like in book 3, the action of which takes place among the non-organic communities of the planet, what an opportunity to just go nuts and yet the whole book is more like an afterthought. This is a series that needs to be read. You just can't really describe it. But people will either love it or hate it. You can support 32nd sci-fi and my other projects by becoming a patron. There's a link in the description below. And visit the 32nd sci-fi Tumblr. That's my headquarters. In addition to my videos, I publish links and updates there every day.
