Implode [edited version]

Exodus Summers has never been the prettiest, most popular person. She's constantly bullied and thrown under the bus, left behind by her peers. She receives threatening letters, which she ignores, on a daily basis. When the letters start getting more personal, she begins to pay more attention.

A sudden string of freak accidents begin to surround her, starting with the people who had been her constant tormentors and she becomes the main suspect. One accident ends in a murder, and the slow downward spiral leads to a full on implosion.
