Doctor Who: Borrowed Time - Naomi Alderman, BBC Books

WHATEVER YOU BORROW MUST BE REPAID... 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 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. Scenting something sinister, 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.Borrowed Time is a thrilling race against the clock from Naomi A Alderman, the Bailey's Prize winning author of The Power featuring the Eleventh Doctor, Amy and Rory, as played by Matt Smith, Karen Gillan and Arthur Darvill in the spectacular hit Doctor Who series from BBC Television. `Alderman is a fluent and powerful writer' - Sunday Times
