Secrets, Lies and A+ Murder

Olympian gods AU-
The mortal gods have to survive their own kind of horror story.

Twelve teenagers. One school. One body. One murderer.
When twelve students of Olympus High get trapped in school over night and find a dead body, panic and suspicion arise, because the murderer is either hiding somewhere in the building, or it's one of them. And to survive the night, they have to work together, which could prove difficult, considering they all hate each other for one reason or another. With everyone from the highest to the lowest of the food chain present, things are predetermined to go bad. Because seriously, when did anyone see jocks, cheerleaders, nerds and loners work together?
And if every last one of them has a dark secret they'd do anything to protect, can they even survive each other?
