There are things much larger than fate... Louis Tomlinson is a street musician with a minor drug addiction and a ginger cat he sometimes talks to. After a nearly fatal beating, he is saved by a fallen angel named Harry. Louis shows Harry how to live and be reckless, while at the same time finds himself falling in love with the beautiful immortal. But there are dangers that lurk in every corner. Can Louis finally let go of his addiction and get rid of the drug dealer who's after his life? Will Harry ever tell Louis his secret? One that he's kept for hundreds of years? A secret so dark and gratifying, it could cost them thier lives? The boys like playing with fire; its beautiful and bright. Lust, hate, passion, jealousy; it is all very dangerous. Their love is merely a blaze, and they are moths drawn eagerly to the burning element. But if one is not careful, everything could all smolder and burn.
