On Monday afternoon, five students at Bayview High walk into detention. Only, Simon never makes it out of that classroom, because before the end of detention Simon is 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? With each character having their own secrets that could act as motive, the hunt to figure out the truth gets more intense with each clue that gets revealed throughout the book.
