Kate concussed after the purse-snatch (p. 716)

The apparition spun itself violently around, trying to shake off Ruth van Cleve, and her/its spin with her purse took the strap-attached Kate Gompert (who didn’t weigh very much) out around in a wide circle (she’d had a flashback of reminiscence back to Crack-the-Whip at the Wellesley Hills Skating Club’s rink’s ‘Wee Blades’ Toddler Skating Hour, as a child), gaining speed; and then a rust-pocked curbside lightpost rotated toward her, also gaining speed, and the sound was somewhere between a bonk and a clang, and the sky and the sidewalk switched places, and a violet sun exploded outward, and the whole street turned violet and swung like a clanging bell; and then she was alone and purseless and watching the two recede, both seeming to be shrieking for help.
