With the spectre of a Nazi invasion looming over Britain, three children are forced into an unlikely allyship in this gripping wartime tale from multi-award-winning author Tom Palmer.

June 1940 – after the devastating defeat of the British forces at Dunkirk, the terrifying prospect of a Nazi invasion of Britain seems ever more likely. In these dark days, three children whose parents are involved in top-secret war work are brought together in unlikely ally ship, covering for their parents and facing down malicious gossip as they come under suspicion from their local community.

Forced to confront the brutal realities of war as it affects every aspect of their lives, the children find the courage to play their part, rescuing survivors and refugees at sea, and undertaking river patrols to detect German E-boat incursions.

But when it appears that the invader is at their shores, will they be able to pull off the most daring feat of all?
