Fifty-One, from south London writer Chris Barnham, is a mind-bending, time travel love triangle, set in past and future London, which has been compared with the classic 'The Time Traveler's Wife.'.

Jake Wesson is sent back from 2040 to Blitz-era London, to stop the assassination of Britain's war leader, Winston Churchill. The assignment complete, the jump home goes wrong, stranding Jake in war-ravaged 1944. Stuck in the past, Jake tries to blend in. He clings to the one familiar face he can find, Amy Jenkins, a war widow whose life he saved. Drawn to each other by loneliness, thrown together amid the terror of war, Jake and Amy look to a future together.

But Jake's future cannot let him go. When his bosses finally find him in 1944, he faces a terrible choice: risk unravelling the modern world...or let Amy die.

Fifty-One is a page-turning blend of science fiction thriller and grittily realistic historical romance.
