To Kill a God

What if magic were real, and humans were a myth?

Al Ardito, the son of an infamous family of gangsters, and his brat of a younger sister, Sophie, find themselves dragged into a strange world by an incompetent gnomish wizard. In this world humans were once worshipped as gods, but those religions have been dying off as new technologies and ideas arise. Now everything will be thrown on its head as two bonafide humans--who want nothing more than to go back home--pop up out of thin air.
