Cat Core

Cat Core follows Florence Valentine, an elderly woman who dies and is reincarnated as a dungeon core. Instead of an afterlife, she finds herself able to create and decorate a dungeon, along with crafting her greatest love -- kitty-cats!

However, this new life isn't without its challenges. Adventurers and other unwelcome guests keep invading her home. In the second book, Florence's return to her dungeon is marred by a problematic bargain with a lich which results in numerous enemies intent on destroying her and her home.

Book three sees her forced on a road trip to find the source of the lich’s power, facing further enemies including guilds and even a grieving king. She aims to use her new hybrid core powers to stop the lich, accompanied by her kitties, along with the friends she has made.
