You All Die Tonight

Picture the scene; seven people wake up in a remote mansion, with no idea how they got there. A disembodied voice tells them they have been gathered there because of their connection to the murder of three people, four years previously. One or more of them is guilty, and the voice wants them to confess in order avoid consequences.
What follows is a fast paced, white knuckle ride of a thriller. The story unfolds along two timelines, now and four years previously.
None of the characters are particularly likeable, though some are more odious than others. Some of them have a secret from their past they would like to keep hidden, and each of them has a possible motive for the murders.
The story is crafted so well that when the final reveal came it stopped me in my tracks. I was so sure I had it right! Hats off to you Mr. Kernick, I didn't see that one coming.
