A killer of influence

Following a convention in the Scottish Highlands, eight social media influencers vanish without a trace, leaving their followers - and families - in a state of shock, and the police clueless as to their whereabouts. And then, the livestreams begin. Broadcast live from their squalid underground cells, the young influencers are forced into a sadistic battle for survival. With each livestream, their captor pits them against each other in a twisted competition for likes. The influencer with the fewest positive reactions faces a gruesome end - live on camera. As the likes increase and the death toll rises, DCI Jack Logan and his team must traverse both the Scottish wilderness and the darkest corners of the internet to try and save the remaining captives. But how do you catch a killer who is always one click ahead?
