From the book jacket:
Facing a seemingly endless war, fifteen-year-old Louisa Adair wants to fight back, make a difference, do something--anything to escape the Blitz and the ghosts of her parents, who were killed by enemy action. But when she accepts a position caring for an elderly German woman in the small village of Windyedge, Scotland, it hardly seems like a meaningful contribution. Still, the war feels closer than ever in Windyedge, where Ellen McEwen, a volunteer driver with the Royal Air Force, and Jamie Beaufort-Stuart, a flight leader for the 648 Squadron, are facing a barrage of unbreakable code and enemy attacks they can't anticipate. Their paths converge when a German pilot lands in Windyedge under mysterious circumstances and plants a key that leads Louisa to an unparalleled discovery: an Enigma machine that translates German code.
I don't often quote from the jackets but this summed it up better than I could. The characters are engaging and I loved Louisa and Ellen. The plot development was perfect, fast paced enough to keep me turning the pages. Also, the description of Scotland the inn where they are staying is so vivid I could see myself at a table enjoying a pint.
This is the second book by Wein which follows Code Name Verity but it can be read out of order. Much thanks to Joy for introducing me to this author.
