Why did I not mention this before?
It's out. Now. And I am one small cog in the great machine.

While US buyers can go here - http://www.amazon.com/Hidden-Horror-Celebration-Underrated-Overlooked/dp/0991127900/ref=sr_1_1?ie=UTF8&qid=1389144000&sr=8-1&keywords=hidden+horror+101
And people in other territories . . . . . . . . . well, I don't know EVERY URL but I'm sure it's available to you if you seek it out, so please do seek it out.
And remember, using a link on this blog to pop over to Amazon and browse and buy anything does end up getting me pennies so if you did happen to purchase this fine tome, and did so via one of the links above, I'd be doubly delighted.
Give it a go. You might just like it.
