Molly was dressed in her battle coat, which consisted of a shirt of tightly woven metal links, fashioned by her mother out of titanium wire. The mail was then sandwiched between two long Kevlar vests. All of that was, in turn, fixed to one of several outer garments, and in this case she was wearing a medium-brown fireman’s coat... She had half a dozen little focus items I’d shown her how to create, none of which were precisely intended for a fight. Her face was a little pale, and her blue eyes were earnest.
