But when Eva falls in love with Graham St. John... she finds herself slipping into a web of intrigue, spies, and secrets. Her journey will test the limits of her friendship with Precious--and the mettle of all Britons as the Blitz devastates their world... Eighty years later, in 2019, journalist Maddie Warner... travels to London to interview Precious.
