London, 1926. Two baby girls are born just hours and miles apart. One you know as the Queen of England, but what of the other girl - the daughter of an undertaker named in her honour?
Betsy Sunshine grows up surrounded by death in war-torn London, watching her community grieve for their loved ones whilst dealing with her own teenage troubles...namely her promiscuous sister Margie. As Betsy grows older we see how the country changes through her eyes, and along the way we discover the birth of a secret that threatens to tear her family apart.
