After centuries of war, loss, and miracles, Helena Potter — the once-mortal Master of Death — finally tires of existing between worlds. She has outlived her era, outloved her purpose, and seen every ending imaginable. So when her patron offers her a quiet retirement for a while, she takes it. The bustling city of Orario, where gods walk among mortals — she steps into it, taking on the old title she once inherited: Hel, daughter of Loki and ruler of the dead.
