This is the second book in the series and whilst it still includes all three WRENS (Iris, Mary & Sally), this book primarily focusses on Mary. She is still grieving for the boyfriend she lost when the Royal Oak was torpedoed in Scapa Flow, close to where she is now based. She is strong willed and presents a no nonsense, tough exterior, though underneath she is still grieving from the loss of Owen and the life she could have had.
A handsome sailor named Joe who is stationed nearby is keen on Mary & whilst she is not interested in romance, they become good friends.
As the girls are joined by more trained Wren’s, they are able to have a little more free time to socialise and plan to spend Christmas with their new friends Elspeth & Archie who are Orkney residents.
Following on from the previous book, the girls find further evidence that there is a spy on Orkney & when German vessels seem to breaking through the defences, suspicions are raised and when an incident occurs that affects some of the people they’ve come to care about, the girls ramp up their investigations. The identity of the traitor was pretty obvious from book 1, but the storyline plays out fairly well.
There are some new secrets and revelations in this book, and just enough open ends for book 3, which should primarily be Sally’s story.
Ultimately this is an engaging historical novel that fits well into its genre and the location of Orkney and the role of visual signaller makes it a little different to other similar books. The characters remain interesting, and realistic, whilst the Christmas storyline is heartwarming and you just know that things will work out happily “because it’s Christmas”!
The book will definitely appeal to fans of WW2 historical fiction, particularly those who enjoy the story of women from different backgrounds coming together to do their part in wartime.
