The Resurrection of Eddie Munson

Wayne Munson had always loved his nephew and has done the best he can with raising him in his brother's absence. But now Eddie is dead, and the world is literally ending. Hell is on earth, monsters have taken over Hawkins, they've been locked in and left to fend for themselves, ash is raining down from the sky, the ground is opening up to swallow them whole, and the last people he ever expected to be with in the apocalypse was his ex and his ex's boyfriend.
