The Knight Watch by Thomas D. Lee

A thousand years ago, the Knights of the Round Table made an oath to protect the realm forevermore.
It's safe to say they didn't think it all the way through.

Now Britain is embroiled in the Second World War, and the knights are still fighting the enemies of the realm. They're also fighting each other - Kay and Lancelot haven't spoken since Agincourt, and everyone wishes Agravain would stop speaking entirely.

Isolde - known in myth and legend for her tragic romance with the knight Tristan - is fed up of her tragic reputation. In a time when women have more freedom than ever before, she's determined to strike out on her own. But when she discovers old enemies working alongside the Nazis, she realises she can't fight all of them by herself. It might be time to get the old band back together . . .

From the Sunday Times bestselling Thomas D. Lee comes this sharp and witty caper, asking what happens when knights in armour return to fix the problems of a more modern world . . .
