Pretty Little Liars meets The Breakfast Club” ( in this “flat-out addictive” (RT Book Reviews) story of what happens when five strangers walk into detention and only four walk out alive.

Pay close attention and you might solve this.
On Monday afternoon, five students at Bayview High walk into detention.
Bronwyn, the brain, is Yale-bound and never breaks a rule.
Addy, the beauty, is the picture-perfect homecoming princess.
Nate, the criminal, is already on probation for dealing.
Cooper, the athlete, is the all-star baseball pitcher.
And Simon, the outcast, is the creator of Bayview High’s notorious gossip app.

Only, Simon never makes it out of that classroom. Before the end of detention Simon's dead. And according to investigators, his death wasn’t an accident. On Monday, he died. But on Tuesday, he’d planned to post juicy reveals about all four of his high-profile classmates, which makes all four of them suspects in his murder. Or are they the perfect patsies for a killer who’s still on the loose?

Everyone has secrets, right? What really matters is how far you would go to protect them.

            I was left on a cliff hanger at every chapter, switching from swooning to gasping and back again. Best thriller I've read in ages

              4/5: THIS BOOK IS AMAZING! Normally I steer clear of mysteries or any books where you have to solve who did it. However, this book did it for me. I have no problem picking up another one in the near future. This had mystery, suspense, and romance all together in one. What more could I ask for? From the first page to the last, I was on the edge of my seat. As the characters grew and more secrets were revealed, I was trying to put the mystery together myself. The 3 main characters are nothing alike and somehow they became friends. They learned who their true friends are and what to do in difficult situations like these. They held their ground even though they were doubted by everyone around them. I personally had doubts for all of them, but definately didn't think they all had worked together to take out Simon. But when I found out who did what.... I was really shocked, that was probably the best plot twist I have read all year!
