I have quite a few novels:
Genre: High Fantasy Medical Drama
The title of Sky Garden is less of a metaphorical meaning and much more of a literal meaning, in the fantasy world I made, a war of the gods cause all of the landmasses to be shot into the sky and are perpetually hanging there in the sky, so the kingdoms became gardens in the sky...so...Sky-Garden.
Genre: High Fantasy Graphic Horror
The title for Deathblooded is a very story involved meaning. The MC is the bad guy of the story, a dangerous, blood-thirsty and extremely powerful assassin who has necromancy magics in spades, one of their titles they have is The Deathblooded General. So they use Deathblooded as their assassin name.
Genre: High Fantasy LGBT Romance
Now, this one...Shrouds and Stilettos, the name was based on the phrase Cloak and Dagger, The phrase means something enshrouded in mystery, intrigue and often spy work, but most importantly, secrecy. The couple of the story are two princes: one a fairy and the other half-elf and half-dragon, the two's kingdoms are at war with each other for decades and the half-dragon prince offers his hand in marriage to the fairy prince to stop it. The two have to go through droves of secrets and mysteries to find out what caused the war.
Genre: Low Fantasy Magic College Slice of Like +POC LGBT MC
Now, Paradise Academy not only is the name of the story, but the name of said magic college, it was called Paradise Academy because the people that started the school picked that name because they wanted the school to be a paradise for the students: somewhere they didn't have to be afraid, could just be regular people and not worry about others seeing their magical abilities or things of that sort.
Genre: Low Fantasy Goth Drama/Comedy
The Weirdos in 1642 I feel like that title is pretty, self explanatory. The story was inspired by the Addams family, the Munsters and similar stories of that random goth family in the neighborhood, but there is more to their story as they...may not be entirely as they seem and the town they move into is extremely 50s Americana style, but is modern, so...the family is refereed to as The Weirdos in 1642.
Genre: Science Fiction Futurism Romance
Rain...it's a super simple title, but with the story, the world was ruined by global warming, leaving the world these dangerous, extreme examples of all different biomes: deserts so hot the sand melts to glass, tundra so cold that the snow forms needles in the wind, amongst other things of that sort. The MC is from a city/country formed in the ocean, to escape the heat and weather, the city was built in huge glass domes under the surface and because of how the world is names like: Rain, Sea, Wave, Leaf, Tree, Stone, Sun, Cloud...environmental names are common, Rain is the name of the MC. His fiance's name is Scarlet and all of her siblings are named after shades of red because they are from a desert city that was built underground and using the sun to their advantage. Because the cities did this to escape, they altered their DNA with genes of animals resulting in animalistic forms: the MC Rain, his family has adapted to the ocean via oar-fish DNA, Scarlet's family are king cobras. So...the title being Rain and the MC being named Rain, felt fitting.
