A debt collector can tell you precisely.
Lirium plays the part of the grim reaper well, with his dark trenchcoat, jackboots, and the black marks on his soul that every debt collector carries. He's just in it for his cut, the ten percent of the life energy he collects before he transfers it on to the high potentials, the people who will make the world a better place with their brains, their work, and their lives. That hit of life energy, a bottle of vodka, and a visit from one of Madam Anastazja's sex workers keep him alive, stable, and mostly sane... until he collects again. But when his recovery ritual is disrupted by a sex worker who isn't what she seems, he has to choose between doing an illegal hit for a girl whose story has more holes than his soul or facing the bottle alone--a dark pit he's not sure he'll be able to climb out of again.
