Solving a murder can get dicey.

Wren Winters is thrilled when her gaming group is invited to join the town's new superstar streamer Noelle Williams for a live demo—after all, a little publicity could put Wren's board game shop, the Cardboard Sheep, on the map. But moments before they go live, Noelle collapses on camera, and by the time Wren arrives at her house, Noelle is dead and the police are swarming.

Detective Greene, who still remembers last summer's murder at Wren's shop, is back with questions—and suspicions. As Wren and her friends reel from the shock, secrets about Noelle's life emerge: relentless online harassment, jealous exes, and a sister desperate to pull her offline. Then another member of the group falls ill with similar symptoms.

With danger closing in and a game board full of suspects, Wren refuses to sit on the sidelines. She's determined to solve the puzzle before her friend's game is over for good.
