Classic story help!

I remember there was this one story I remember reading in episode like back in the day when classic style stories were popular. There was one that was like a vampire one but I cannot for the life of me remember the title. I think the MC’s name was Primrose with brown hair (I think??) where she turns into a vampire after and I think the title had bite or something in it. I also do remember it being a little explicit with the writing. Does anyone know which one I’m talking about??
