My current main novel is inspired by my absolute hatred of mainstream omegaverse stories- wattpad novels and manga mostly. I hate that the omega is always portrayed as weak, especially in the LGBT/BL genre, and that rape is glorified as romantic and a plot device to get the main characters together at all costs- I wanted to completely turn that on its head and let the omega come out on top (...eventually).
My other story here is inspired by characters yanked out of failed novels. I really loved them, and I really love dragons, so that came together naturally. I'm very character driven and stories form around that.
I also have a 14ish book series I'm chipping away at, and the main reason I'm writing it is because I got a very angry message on wattpad about how I disrespected religion by writing about a demon and an angel together, and I said 'eff that' and planned the whole series to make that person as angry as possible.... though it took on an unexpected depth to it, lol, lots of challenge morals.
... apparently I'm inspired a lot by petty anger, lol, but I do draw from music, television, etc.- usually because I can't stand the way somebody else used an idea and want to use it better (maybe I'm a jerk...)
