" People talk about books being an escape, but here on the tube, this one feels more like a lifeline. As she leafs through the pages, the rest of it fades away: the flurry of elbows and purses, the woman in a tunic biting her fingernails, the two teenagers with blaring headphones, even the man playing the violin at the other end of the car, its reedy tune working its way through the crowd. The motion of the train makes her head rattle, but her eyes lock on the words the way a figure skater might choose a focal point as she spins, and just like that, she’s grounded again. "
