Loving Mona Lisa {Niall Horan FanFic}

Mona Lisa was forced to run away from everything she ever called home. Now she is on the streets, running away from someone or something, with nothing to keep her company but grief and raw terror.
Then she bumps into Niall Horan, worldwide popstar, and maybe, just maybe, her life will change.
Will she fall in love? If she does, will she be caught? Will she find herself, or will her depression swallow her? Will she make a new life for herself, or will she be caught by those who chase her? Will she open up and trust the One Direction boys, or will her biggest secret remain hidden?
