Hazbin Hotel (Alastor x Maddie) (My OC)

This book follows Charlie, the princess of Hell and her sister, Maddie, as they pursue their seemingly impossible goal of rehabilitating demons to peacefully reduce overpopulation in their kingdom. After a yearly extermination that was imposed by Heaven, they open a hotel in the hopes that patrons will be "checking out" after proving their souls are redeemable.
