Demon House: Pretty literal xD The main character is renting a place haunted by demons.
Heavy Horns: The main character has bull horns and the burden of having them has affected his life, in some ways positive, but he still suffers some hindrances.
Erie Waters: A play on words. It's a paranormal romance that happens on the shores of Lake Erie.
At Ease: Also a play on words. It's a paranormal romance between a guy and a ghost soldier.
Sarota Springs: It's the name of the town the story takes place in.
Secunda: This one requires a bit more explanation. It means 'second' in latin. One of the themes in the story is having a second life. The main monster quite literally is in his second life as his original body shattered and now he's in a new state of being. The protagonist is entering a new stage in life as well after a period of isolation, and her meeting the monster basically jump starts a new beginning for her. Now, I chose a latin word for the title because the story is about a cryptid-like species and there are other ties to natural history so I wanted something to link to scientific nomenclature.
