So, funnily enough, the protagonist is the only character in this book that sucks. Leila kind of does at first too, but later on she seems much more human than Abby, the main character. It starts out with Abby being a bitch to her sister Gabriella about joining the Tri Gam sorority. Gabriella doesn’t want her to join. Then Abby’s mom comes in to talk to her, but she never says anything to Gabriella, which is significant.
The book essentially takes place over one night with the Tri Gam pledges completing their initiation. There’s Leila, who Abby believes stole her former boyfriend Gordon from her. There’s Nina, who is a childhood friend of Abby’s. Jessie is the laissez faire one that doesn’t seem to know social decorum. And there is Andrea, the TG leader. There are other girls, but they aren’t as relevant to the plot.
So, to become TGs the girls must all rob a store. Pledge Ruby declares that she is staying home and not being a part of it. Leila is positive it’s all a joke. They draw straws to see who will end up holding the pistol. Nina gets that delightful job. Because she’s a cunt, Andrea waits outside and makes the girls do her dirty work.
While inside they smash the cases to get the jewelry, and then the owner, Mrs. Driftwood, comes out. The girls try to tie her up but instead end up making her have a heart attack. Jessie confirms that she’s dead.
The girls head back to the house with Andrea, unsure what to do now that their initiation took such a wrong turn. Andrea tells them to remain calm, and Nina suggests they call the police. Andrea calmly reminds them there is no phone in the house. Then all the girls start blaming one another for what happened.
Also, Gordon is around, having showed up to spend time with Leila. Abby, however, is convinced he’s there for her.
Then Andrea turns up dead with Jessie once again confirming the death. Now the girls really don’t know what to do. Then Gordon shows up at the door soaking wet. Nina and Jessie saw him run around the house and say he killed Andrea. Gordon has no idea what they are talking about, and Abby confesses that he was with her.
Except... he wasn’t. Abby is deluded. Leila tries to tell her this, but she will not listen. The girls lock Gordon in a room until they can figure out what to do with him. Then Leila demands to talk to Abby upstairs.
But when Leila finally makes it upstairs, she doesn’t find Abby... she finds Gabriella. She finds Abby saying she’s Gabriella. Yep, good old Abs has a split personality. The worst part? We are given no explanation for how it was brought on or caused other than Leila “stealing” Gordon from Abby. Way to set back the feminist movement, Stine.
Gabriella/Abby now has the gun, and she forces Leila to the basement. But she doesn’t anticipate Gordon being there. They all three start to fight. Up above, the other girls hear the scuffle and head downstairs. Everyone, including the reader, is very confused at this point. Gordon finally gets Abby/Gabriella subdued.
And then... Andrea shows up at the top of the stairs. What? Yep, Leila was right all along. The whole thing was a sick joke. They pull the stunt every year, and Mrs. Driftwood is also in on the gag and therefore not dead (what a sadistic old lady). Nina berates Andrea for the terrible prank, which Andrea assumes to be her resignation from the TGs. Nina says no fucking way-she’s not leaving now! Instead, she plans to outlaw the prank from every happening again to other pledges.
But Leila is out. She can’t take it anymore at all. She tells Gordon she just wants to be with him and finish school. Then she hugs Abby/Gabriella and apologizes to her for everything. Abby is taken away in an ambulance... with Gabriella right by her side “reassuring” her it’ll all be all right.
