50. To Your Scattered Bodies Go, Philip Jose Farmer * Read the whole series, the whole series was good. It did start to get slow in the second book, even when it got slow it was still good. This first one was the best one.
I've read other books by many of these authors, and other books by other authors. Considering how big of a Sci-Fi fan I am, I am embarassed by how few of these I have read. I've seen moves to at least six of the books mentioned not counting the ones I have read. I've now got some time to read again, and I intend to do it. I've got some Stephen King to get out of the way first, then I'll delve back into Sci-Fi. Asimov is at the top of my list, as it stands the only book of his I've read is The Positronic Man (Bicentenial Man to movie watchers).
