Verenice took off her gloves and half-closed her eyes. She whispered something, her voice rising at the end like a question. Then stumbled back, sliding on the snow, and fisted her hands closed, breaking the spell. “What is that?”
Okay so this is the second use of "fisted" I've seen in this context and I may have the immaturity of a middle schooler about things like this, but this does not seem like a use of the word I have ever heard before, much less twice in relatively quick succession. It's one thing to describe someones hands as "fisted by their side" (a future use in this book) and another to use it as an active verb.
