Reaper
Don't mess with Death, he doesn't like it.
Don’t deal with demons, don’t kill with magic, don’t bring back the dead. There are three simple rules that every magic user knows and abides.
Powerful families enforce the rules, and the only sentence is death. When a novice mage is offered immortality in exchange for breaking them; he jumps at the chance.
Now he must navigate a world of politics, monsters, and dark gods with only his familiar to guide him. But she has plans of her own.
