published a book about Corpsie
Posted 3 years ago....what the title says.
While it is SFW, it does contain a substantial amount of gore (comes with the main character being a monster bodyguard)... and resides within the black comedy and dark fantasy genres.
I wouldn't 100% call it horror... and it's quite cute and wholesome at times.
Anyway I hope it's good, and if you're curious, feel free to give it a preview (I believe you can read the first 2-3 chapters for free) on Amazon :D
