"Like Inglourious Basterds for tweens, this clever YA title features Sarah, a blond, blue-eyed Jewish girl in 1939 Germany."--The New York Post

     After her mother is shot at a checkpoint, fifteen-year-old Sarah finds herself on the run from the Nazis in Third Reich-ruled Germany. While trying to escape, Sarah meets a mysterious man with an ambiguous accent, a suspiciously bare apartment, and a lockbox full of weapons. He's part of the secret resistance against the Reich, and he needs her help.
     Sarah is to hide in plain sight at a boarding school for the daughters of top Nazi brass, posing as one of them. She must befriend the daughter of a key scientist to gain access to the blueprints for a bomb that could destroy the cities of Western Europe, and steal them.
     Sarah may look like the rest of the girls, innocent, blonde-haired, and young, but she refuses to become one of the monsters she's surrounded by. She's a brilliant con artist, convincing them she's one of them even as she lives in terror of being found out. And she's determined to get her revenge on them all. “A stunning, smart, grounded tale of intrigue in Nazi Germany, so guilty and detailed it feels like true memory rather than fiction. Sarah is an angry, appealing, heart-wrenching hero, superhuman and achingly frail in equal measure. I wish I’d written this myself. Deeply disturbing and chillingly good.”—Elizabeth Wein, New York Times bestselling author of Code Name Verity

 “I found myself mesmerized by Sarah’s journey into a world of human monsters. Orphan Monster Spy weaves one heroine’s courage through a spectrum of darkness, and the effects resonate long after the final page.” —Ryan Graudin, award-winning author of the Wolf By Wolf duology

“Killeen expertly conjures the day-to-day evil of Nazi Germany in this terrific page turner.”—Paul Dowswell, award-winning author of The Auslander

"A powerful, bleak, and penetrating portrait of an isolated young woman excelling in unimaginable danger."—Kirkus Reviews
