Shatter me / Tahereh Mafi.

Set in a dystopian world, Shatter Me is the story of a 17-year-old girl imprisoned for possessing a fatal touch. As she watches everything crumble around her, she must choose between relinquishing her power or using it to save the world. Juliette hasn't touched anyone in exactly 264 days and the last time was an accident. Now accidental murder has her locked up in an asylum where happy is a hot meal and not being dead in the morning. No one knows why touching her skin for too long is fatal. No one knows how to fix her problem. No one really cares. The world is too busy crumbling to pieces to pay attention to a 17-year-old girl. Diseases are destroying the population. The ozone layer is deteriorating. Farms are scarce, food is hard to find, temperatures are unreliable and the clouds are the wrong colour.
