A Book of Dust and Breath

Max has spent the past several thousand lifetimes as a Reaper among humans and, despite the pleasures of a tidy country home with a well-dusted library and a finely tuned Harley, he's starting to get bored. His best friend gives him some advice: "Drink some scotch. Bed a woman. Join a rock band. Get it out of your system, and get back to your dutiful service."

Max tried, but he ended up getting drunk, marrying the girl in Vegas, and accidentally triggering a chain of events that could end with the destruction of the human race.

Now he needs to make things right again but the Reaper quickly learns that the magic of being human comes with one grim reality.
