Larry Stylinson and Niam, With a Pinch of Zirror: a One Direction FanFiction

What happens when Harry's best friend from Cheshire, Susan, comes to stay with the band by invitation of Louis? She may have a deadly disease, but she still manages to shake up the boy's "friendship" enough to turn it into something more. With Niall and Liam as her accomplices, how will the boys of One Direction stay sane? Well, the answer is simple... They don't. Zayn, meanwhile, prefers to stay in the world of his mirror. Some lad's never change.
