Tainted horn and bareback heart: who is exterminating the unicorns? (full chapter)

What kills the sex unicorns off?  What is the touch of their horn that brings them death and destroys their magic?

The silver bullet: How to fool a unicorn (extract)

Here is where I tell you how to take down the hard to capture unicorn.
