The Mary Shelley Club by Goldy Moldavsky

Rachel has a secret, and she wants to keep it that way. She is starting over at a ritzy private school in New York. She is not wealthy like most of the other students which sets her apart. Wanting to belong, she becomes intrigued by the rumors of an unknown prankster who takes revenge on people who deserve it. 

It doesn't take Rachel long to figure out that there is a group who pull the pranks. It turns out they like horror movies which Rachel also loves. She became fascinated with such movies after the thing happened...you know, the secret that caused Rachel and her mom to move. 

Not everyone wants her in the group. They are a mix of people you never see together at school, and they feel very exclusive. The guy who fights for her inclusion is interesting to her. He is not rich either and a kind of cute. 

The club is all about a competition to pull off the best fear test on someone outside the group; find their biggest fear and create a situation that will get them to scream. It's a scary, dangerous game for all concerned. Even though Rachel was hoping the group could help her deal with her past, it may be the worst thing for her.
