Seven Ways We Lie By Riley Redgate

Seven students. Seven (deadly) sins. One secret.
Paloma High School is ordinary by anyone’s standards. It’s got the same cliques, the same prejudices, the same suspect cafeteria food. And like every high school, every student has something to hide—from Kat, the thespian who conceals her trust issues onstage, to Valentine, the neurotic genius who’s planted the seed of a school scandal.
When that scandal bubbles over, and rumors of a teacher-student affair surface, everyone starts hunting for someone to blame. For the seven unlikely allies at the heart of it all, the collision of their seven ordinary-seeming lives results in extraordinary change.
