The Rose Code by Kate Quinn

The mistress of intriguing historical mystery has given us what I believe to be her best book to date. Three women from very different backgrounds and personalities come together in the most unlikely place - Bletchley Park where top secret codes are hacked and passed on. As is her way Quinn presents a dual timeline 1940 and 1947. Osla saddled with the "Dizzy Deb" handle she hates, statuesque Queen Man who doesn't put up with anything from anyone and mousey Beth who is desperate for a life away from taking care of her domineering mother. The three part ways after a friendship crushing accident and unshared information but in 1947 it is up to Osla and Mab to put aside their differences and come to the aid of one of their own as well as solve a mystery that has haunted one of them. This is another adrenaline- filled story with tough smart women who manage to forge ahead in a time where women received none of the glory and were forced to remain silent witnesses to the history unfurling around them. Amply researched, hugely entertaining and enlightening, Kate Quinn's books strike just the right balance between fact and fiction. You will be missing much if you skip the author's note at the end to find out more about her muses and her research.  5 stars
