So, I'm having a little trouble fitting my newest piece in a [few] genres. It has aspects of Science Fantasy, Historical Fantasy, Alternative History, and Apocalyptic. So should I market it as Fantasy or Speculative Fiction? And age: YA or NA?
A really rough "about":
Deus (God) creates Earth as a diorama for his wife (Gaia) as an anniversary present. He planned on presented it to her at a party whose guest list included the rest of the gods. The Earth starts with Adam and Eve and ends about this time. Things don't go as planned and it's no longer the perfect "playground" Deus had created (he created it with just Adam and Eve and everything after that was not supposed to happen) and he thinks his kids (the Four Horsemen of the Apocalypse) messed it up so he implores them to fix it before the party. Things, however, only get worse.
Most of the story follows the Four Horsemen (the equivalent of people in their late-teens and early-twenties). There are a few sex/sexual assault scenes.
