One of Us Is Next by Karen M. McManus

This sequel to one of the most talked-about New York Times bestselling thrillers is one to watch! There's a new mystery to solve at Bayview High, and there's a whole new set of rules. In the year since Simon died, dozens of copycat gossip apps have appeared, but no one has been able to fill the void he left behind as he did. People don't have the facts, so that's the problem.

Until now.

This time it's not an app, though—it's a game.

Truth or Dare.

The first target is Phoebe. If you choose not to play, it's the truth. Dark is hers as well.

Next, Maeve enters, and she knows better always choose the dare.

Knox was about to be tagged by the time things became dangerous. If Maeve learned anything from Bronwyn last year, it's that they can't turn to the police for assistance. You can also protect yourself.

Someone at Bayview High wants to preserve Simon's legacy. The rules have changed this time.
