In this speculative YA fiction, war takes the place of apocalypse. American teen Daisy has been sent by her distant dad to spend a summer with her cousins in the British countryside—but soon after her arrival, Great Britain is taken hostage by a group of unnamed terrorists. In the weeks that follow, their life is an unsupervised idyll, as Daisy slowly drops her defenses and falls in love with her cousin Edmund. After they’re separated by advancing war, she makes her way across a treacherous, combat-blighted England in the hopes of reuniting with him.
