No. She'll probably have her shields up most of the time. Unlike me, she's pretty scrawny and physically weak, so someone like Clover could probably kick her ass in about ten seconds, provided she was sans book.

I'm still thinking up a plan for snatching it from her. I'm hoping it doesn't have to come down to "challenge her to a magic fight and then take it when she's injured or unconscious," but it might.
