What would be a good title?

I'm writing a story about this girl and her school has an event at night to play Manhunt with the lights off, but the girls dad locks down the school and it becomes a real Manhunt and she has to stop her dad (very brief summary, i know, put i don't want to give the whole plot away, and it's novel length and very in-depth). It's an adventure, thriller, slight romance novel about teens and aimed for teens, so any possible titles?
