This book had so much potential but was too fluffy with overly trite/simplistic dialogue so none of the characters really came to life.  

We meet Sophie as a teen in Vienna as the Nazis are coming to power.  As her parents realise what is to come, they urge Sophie to take her younger sister and get away.  Sophie (somewhat simplistically) gets recruited by the British secret service to work for them undercover in the library at Windsor Castle.  This novel is essentially a "what might have been, we just don't know..." kind of story, and whilst I'm sure it's true life was (to some extent) simpler then and people more trusting, the narrative just didn't read right to me.

In a dual timeline we have Lacey, an American woman in her 20s coming out of Covid and making a discovery about her grandmother that leads her on a journey to Windsor.

Though I enjoy historical fiction, the clunky dialogue and too much suspension of belief marred this one for me and it just didn't hit the mark
