One Child in Berlin (Stella Bled Book Three)

From USA Today bestselling author A.W. Hartoin comes a series perfect for the fans of Kristen Hannah's The Nightingale, Martha Hall Kelly's Lilac Girls, and Kit Sergeant's The Spark of Resistance: Women Spies in WWII.

November 1939
It's been a year since Stella Bled Lawrence and her husband, Nicky, escaped Italy by the skin of their teeth and a lot has changed. Nicky joined the Royal Air Force and Stella spent the year training as a spy for His Majesty's Secret Intelligence Service. She has the languages and the tradecraft down pat, but she still has a way to go when the Earl of Bickford pulls her from her training early.
The earl uses his influence to make her a courier, a job well below her skills, but it's not as simple as it seems. The new head of the service isn't convinced of her worth and Stella has to use the opportunity to show him that she and other women can deliver for Britain or she's out on her ear.
That would be enough to make any newly-minted spy nervous, but the earl isn't done. He has a favor to ask and the request sends Stella to a place that will haunt her forever.
