Girl in The Blue Coat by Monica Hesse

Amsterdam, 1943. Hanneke spends her days finding and delivering scarce black-market goods to customers trying to survive under Nazi occupation. She knows how to navigate the city's dangers and, more importantly, how to avoid attracting unwanted attention.
 
Then one of her customers asks for something very different: find a Jewish teenager who had been secretly hidden in her home—and who has suddenly disappeared. Drawn into the search, Hanneke discovers a hidden world of resistance, courage, and impossible choices.
 
Inspired by the experiences of young people during the German occupation of the Netherlands, Girl in the Blue Coat blends historical fiction, mystery, and coming-of-age storytelling into a moving exploration of loss, guilt, friendship, and bravery during World War II.
