Q: One of the Best Books for an introduction to Sci/fi writing. When I first read this book years ago I said that to a friend of mine, and it still holds true today. One of the very few books i will read over again every year or two. Thankfully its just as good then as well. If you want an enjoyable read, that leaves you smiling at the end this is it.
A:
Positive
