well. let me explain.
Crank: A "good" girl goes off the deep end, becomes a cocaine addict...
Burned: A Morman girl is sent away from her family by her dad because she is misbehaving (for wanting to fall in love) and...if I say anymore I would ruin the story.
Impulse: From 3 different POV's, 2 guys, 1 girl, all in a psych hospital for trying to kill themselves some way or another...
They all just end horribly (not that the writing is bad, just the endings are extremely sad)
