Daisy is sent from New York to England to spend a summer with cousins she has never met. They are Isaac, Edmond, Osbert and Piper. And two dogs and a goat. She's never met anyone quite like them before – and, as a dreamy English summer progresses, Daisy finds herself caught in a timeless bubble. It seems like the perfect summer. But their lives are about to explode. Falling in love is just the start of it. War breaks out – a war none of them understands, or really cares about, until it lands on their doorstep. The family is separated. The perfect summer is blown apart. Daisy's life is changed forever – and the world is too.
