"I didn't earn the name Godkiller, but in three days I'll own it." Witches are disappearing all over New York and Ace Dante couldn't care less. Until one holds his friend at gunpoint, demanding Ace take the job. The witch produces a girl's severed arm, bearing an unusual hieroglyph, and Ace starts to care a whole lot more. He recognizes that mark. It's connected to Ace in ways he doesn't yet understand. Why is it on a dead witch's arm? Missing witches and severed arms aren't Ace's only problems. With a new name around his neck-Godkiller-Ace has a promise to uphold. He has three days to kill the god, Thoth. Or risk Osiris's wrath. The last time Ace defied Osiris, he earned a curse that crippled his life and turned him into Osiris's puppet for eternity. This time, Osiris won't be as lenient. Ace must kill Thoth. An impossible task. It takes a god to kill a god, and Ace is just a washed-up mercenary. Isn't he? As the spells are cast and the truth is revealed, there's only one way out. Ace must become the monster the gods fear him to be. The Soul Eater has a new name, and now, nobody is safe.
