Tag, You're Dead by Kathryn Foxfield
From the bestselling author of Come Out, Come Out, Whatever You Are and Good Girls Die First comes an entertaining new thriller filled with knife-edged tension, twists you won't see coming, and contestants who will do anything to win―even something deadly. When teen social media influencer Anton Frazer stages a live-streamed, citywide game of Tag where the prize is to become one of his live-in personal assistants, his fans go wild. Outfitted with body cams, GPS trackers, and pressure sensors to keep tally of who's disqualified, contestants are split into Chasers and Runners then let lose into the night-covered urban jungle to hunt each other down. While the whole world watches. Four contestants, however, have alternative motives for joining the game, secret reasons to want to win despite the risk: money, obsession, fame…and revenge. One of them will stop at nothing to be the victor at the end of this adrenaline- and fear-fueled night.-Goodreads
