Amber (our narrator) wants to compose movie soundtracks. She is desperate to find a way into USC's music program. Since she started high school, Amber has been trying to be herself without being known as the sister of the girl who killed herself.
Robbie is a popular athlete. He dreams of going to Georgia Tech to play baseball just like his brothers. Robbie's father has never given him the attention and respect he gave his other successful ball playing sons. Robbie wants to make it on his own to prove his worth.
Diego is smart. He invented a color changing sponge that has sold well enough to make him a millionaire. To do that, his dad left the company he started with Amber's father causing Amber's family to suffer financially.
Sasha is the top of the popularity pyramid at school. She wants to go to Harvard, so she involves herself in every activity and is usually in charge of them. Sasha is ambitious and ruthless, but her friends are loyal even when they are on the receiving end of her wrath.
Priya was Amber's best friend. She was perfectly happy when it was just the two of them, but she encouraged Amber to approach Sasha about writing music for the school play. To do so, they must become a part of the popular crowd - a decision Priya would regret.
Scott is the outlier. He is only driven to smoke weed and cruise through school. He's not a stoner oblivious to what is going on around him. Still, the others wonder why he was invited to this 'party.'
The story is played in two ways: the time in the locked room and flashbacks leading up to it. Each add to the intensity as truths are revealed. In the room, tempers flare causing violence. So many questions to be answered: Who invited them? Who would want one of them dead? Is the bomb real? (ya, I hadn't mentioned that part yet or the syringe). If you are looking for a book full of suspense, give this one a read.
