We already have Winifred’s book. Would it be too much to ask (or beg desperately, in my case) for Sarah Sanderson? She’d probably be a Charmer, just because she definitely has a way of charming people. She charmed me. Her attacks would be different spells, which would be easy enough to figure out with a dose of imagination (or ripping off Harry Potter, because that’s understandable).
And to further the point of me literally begging for her, I would easily waste an entire paycheck trying to get her character. Sarah Sanderson is my personal Disney princess and I will hear nothing otherwise.
