Louis is an angel who is just a little too bad to be good, Harry is a demon who is just a little too good to be bad, and they're both a little too in love to be impartial when angels and demons go to war.

Louis has been alive since life was a mere concept; he watched the summoning of Man into existence, he was there when Eve took the apple. He's seen seas break the world into separate pieces, he's watched empires crumble into dust. He's seen wildfire consume cities, he's seen the world painted white with snow. He has known the most beautiful humans to walk the planet, he has watched the most powerful mortals gather their riches and influence around them and then die just like the poorest, weakest humans do. He's met humans whose motives defy explanation, people who use their lives as battering rams, as tools, as weapons, as chess pieces.

None of that stopped Louis in his tracks.

But Harry did.
