A girl with a telepathic gift finds a boy clinging to his last hope during the war-torn climate of Europe, 1940.

At fifteen, Kit Cavendish is one the oldest evacuees to escape London at the start of the Second World War due to a long term illness that sees her stuck in a wheelchair most of the time. But Kit has an extraordinary psychic power: she can put herself into the minds of others, see through their eyes, feel their emotions, even talk to them - though she dares not speak out for fear of her secret ability being exposed.

As Kit settles into her new life in the North Wales village of Bryn Eira Bach, solitude and curiosity encourage her to gain better control of her gift. Until one day her search for information on the developing war leads her to the mind of Henri, a seventeen-year-old Norwegian boy witnessing the German occupation of his beloved city, Oslo. As Henri discovers more about the English girl occupying his mind, the psychic and emotional bonds between them strengthen and Kit guides him through an oppressive and dangerous time.

There are secrets to be uncovered, both at home and abroad, and it's up to Kit and Henri to come together and fight their own battles in the depths of the world's greatest war.
