Original fiction: probably 'the passion paradox' that's amazing. Umm...'the sunshier' is also a really sweet original romance.
fan fiction: the glass passenger, it's an Alex Gaskarth ff, but not what you'd expect. Bare your bones, although that's just started out with John O'callaghan.
Those are the four that come to mind :}
oh, and anything by formerlyknownas she's amazing!
