London is only just recovering from the brutal war that saw most of the city demolished. Lydia's life has been upended, but much is the same. She still works as a barmaid in her uncle's pub and she's still frozen with indecision on what to do with her life, post-war. Then one night, a man named Nat enters the pub and everything changes. What starts out as harmless flirting, quickly wrenches Lydia into a world where unexplainable things are happening to survivors of the Blitz. In this new world, danger is around every corner and Lydia must choose whose side she's on before her beloved city is torn apart once more.
