Yvonne's up and running before my aching body can even get to its feet. She sprints to the rear of the roof and hops into the seat of her skybike. The headlamps come on as she revs the engine.
"Hurry up, old man!" she yells.
"Smart-mouthed little..." She's putting on her helmet as I climb into the rear seat. The thing's a souped-up old pre-war model that would make a collector drool. I'm hardly even settled in when she kicks the antigrav boosters and we rocket off the roof into the sky.
I cling for dear life to the handholds as the wind whips by. The tails of my new coat billow over the back of the bike. It's all I can do not to look down.
"Came from one of the top windows, in that building with the old satellite station!" I shout at Yvonne over the roar of the wind. "We can find a way in from the roof."
