A sweepingly epic and gloriously intimate commercial debut - a beautiful and haunting story of lost innocence and a powerful, enduring love.
Clarissa is almost seventeen when the spell of her childhood is broken. It is 1914, the beginning of a blissful, golden summer - and the end of an era.
As Tom and Clarissa's friendship deepens, the wider landscape of political life around them is changing, and another story unfolds: they are not the only people in love. Soon the world - and all that they know - is rocked by a war that changes their lives for ever.
