This was a fabulous, well researched, WWII historical fiction, that in a interesting change was told in only 1 time period. It featured two Canadian women (twins), both who joined the Wrens (Women's Royal Naval Service). One was a mechanic & pilot and the other a Morse Code expert & code breaker. There was family dynamics, romance, and heroism and it was not only a wonderful read but a great history lesson. I loved it. Thanks to NetGalley. 4.75/5
