The stakes have never been higher and the game is far from over. Detectives Dylan and Dillon are used to solving high-profile cases, but their latest assignment takes them into the heart of Indiana’s largest tabletop gaming convention: Game Con. What was supposed to be an all-girls getaway for Dylan and her friends quickly turns into a real-life nightmare when a fellow gamer collapses and dies during a high-stakes board game session. As the convention halls of Indianapolis teem with over sixty thousand fans, the body count begins to rise. A second death in a train-themed hotel room and a terrifying "accident" on a rusty fire ladder prove that a calculated killer is stalking the group. Amidst a world of "sarcastic banter and backhanded compliments," Dylan and Dillon must peel back the layers of a close-knit circle of friends where every move is a strategy and every secret is a weapon. With the killer following the script of their own twisted murder mystery, the detectives must win one final round to unmask the culprit before the convention ends—and before the next roll of the dice proves fatal.
