Since I don't have a list of 'full moon novels', I can only speculate. It could contain fantasy novels. The full moon can be a magical element in fantasy stories, perhaps a time when magic is at its peak or when portals to other worlds open. Another possibility is historical novels that use the full moon as a setting element, for example, a battle taking place under the full moon or a clandestine meeting.
I'm not entirely sure which specific novels are in 'full moon novels' as it's not a widely known, common collection to me. However, some popular novel types could include mystery novels, where the plot thickens under the moonlight - so to speak - with secrets and puzzles to solve. Maybe there are also some romantic novels, where the full moon often symbolizes a special moment for the lovers in the story.
Well, without more information about 'full moon novels', it's difficult to say for sure. But generally, in a collection named like that, we might expect some horror or supernatural novels. The full moon has long been associated with the strange and the otherworldly in literature, like werewolves and vampires coming out. There could also be adventure novels where the full moon lights the path for the heroes on their quests.
