'The Squall feed on psychic energy. They spread like a plague and if they are not stopped they will strip the Earth clean…'

London 1910: an unsuspecting thief finds himself confronted by grey-skinned creatures that are waiting to devour his mind. London 2789: the remains of an ancient android are dredged from the Thames. When reactivated it has a warning that can only be delivered to a man named 'the Doctor'.

Borrowed Time by Naomi A. Alderman

'You want more time Mr Brown, of course you do. We all want more time. Let me make you an offer…'

Andrew Brown never has enough time. No time to call his sister, or to prepare for that important presentation at the bank where he works. The train's late, the lift jams. If only he'd had just a little more time. And time is the business of Mr Symington and Mr Blenkinsop. They'll lend him some – at a very reasonable rate of interest.

Detecting a problem, the Doctor, Amy and Rory go undercover at the bank. But they have to move fast to stop Symington and Blenkinsop before they cash in their investments.
