Game On — David Clark

Kidnapped. Tortured. Forced to Play a Game.
 
The ultimate betrayal pulled a group of friends out of the role of players of an online video game and into characters in a deadly game of challenges broadcast for all the world to see via the Dark Web. Friend is pitted against friend for survival. In the end only one can survive and be crowned Game Master.
The Game Master novella series by author David Clark has been called "a darker version of The Hunger Games with a modern spin."
