According to the LA Times she is.
Here is what they have to say:
Meyer and her producing partner at company Fickle Fish have optioned the book’s rights and begun developing the film, with Meyer set to produce (but probably not write), according to a person familiar with the project who asked not to be identified because they were not authorized to speak about it publicly.
I have to admite, I am quite dubious. I liked Anna Dressed in Blood and if I am honest I can't say the same about Meyer. Twilight was not for me it lacked the substance Anna Dressed in Blood has and I am not sure I want her anywhere near it for fear it will turn into a massive romance and loose all its appeal.
Still I could be wrong, we will have to wait and see.
What do you think?
