Now, unfortunately, she had another problem: keeping pace with th  train, her speed zero relative to the train, she was perfectly visible to anyone on board, including Vector’s insect eyes.

Shade dropped back past the rows of windows, to the back of the train. She took a breath and leaped up to the sloped windshield, and had to motor her legs like Road Runner to keep from slipping off. She clawed and clambered up onto the roof to discover her way impeded by the raised framework called a pantograph that scraped along the bottom of a live electrical line running very high current. She gave as wide a berth as possible to the pantograph then trotted forward, easily leaping the gaps between cars, indifferent to the gale-force wind that would have knocked any normal person flat, and flashing on movie scenes she’d seen of people doing just this. Hadn’t Tom Cruise done this in at least one movie?
