A guide to the writing of horror, fantasy and science fiction for aspirant writers written by an award-winning fantasy and horror writer. It also includes lists compiled by Stephen King, Orson Scott Card, Harlan Ellison and Jane Yolen.
The book is a brisk read right up until the chapter on the psychology of horror fiction which, frankly, reads like it was written by a psychologist. It was boring, tedious and felt very out of place among so many good essays.
The only other problem is the chapter at the end that supposedly helps you get published. While I'm sure it was quite helpful at the time it was written (in the mid-1980s), many of the publications it lists are now defunct and many of the practices have changed. It's not a bad section, it is simply past its time.
Regardless, for those who want to learn how to write horror from those who have done it, this book is well worth reading.
