Please check them out. Each book is filled with terrific short stories by many very talented authors, horror-themed stories in Twisted and AI-themed sci-fi stories in The Singularity. Each is a real pleasure to read.
By the way, there was a book launch party for both books on the 18th of December at the Cinema Museum in London, and they filmed a clip of it. I was even included in the video (45 sec mark). We all definitely had a lot of fun that night.
