A dangerous game - Afterdeath
This is the sequel to A Reluctant Partnership. If you haven't read that, I suggest you do so before reading this.
Death, Life, Ink and Error are faced with the seemingly impossible task of finding Geno, who has been taken by Nightmare. They need to follow the clues that might lead them to finding the two.
Meanwhile, Geno is battling for his life to try to hide a secret. If Nightmare finds out, the entire world would be ripped apart.
