Do what you please because at the end of the day this is your work and if people don't like it, then they don't read it, there's no need for any hate on you saying that they "hate the story line or theme the book takes. I think maybe doing a different genre of book altogether would be great and fun for you as there's something different to write, so I really love the idea of the werewolf book. Perhaps you could think of a story line no ones thought up yet, that way no one can say "Oh this has so been copied from the 'Abused Mate' or the 'Silent Luna'"
I love your work and hope this comment helped in anyway! Xx
