Well, I have a vague, passing, very limited familiarity with Catwoman (so would probably miss canon errors) and I wouldn't really have any availability to do it until mid-April time, but if you still needed someone and those restrictions/timescales worked for you, I could beta read for spelling and grammar and for internal plot consistency?

I'm aware that is far from the most ideal offer in the world, but it's available if you want it. I'm equally aware that you might want to gracefully decline and that would be fine too :)
