Wow this book was fantastic! Based on real events in WW2 a group of highly skilled and courageous women were recruited to hide in plain site. This book follows Wren throughout the war and her secret missions. Totally hooked from page one, this was a real page turner, it was tense and exciting and had me holding my breath in places when things got a little bit iffy for Wren. World War 2 stories that have some truth to them blow me away, I can’t imagine living through a war and also finding the courage as a woman to fight. A brilliantly told story, I cannot wait for the next in the series. If the quality of book one is anything to go by, book 2:is going to be a cracker. Highly recommend if I could give it more than five stars I would!
