A Jewish girl-turned-spy must infiltrate an elite Nazi boarding school in this highly commercial, relentlessly nail-biting World War II drama! After her mother is shot at a checkpoint, fifteen-year-old Sarah--blonde, blue-eyed, and Jewish--finds herself on the run from a government that wants to see every person like her dead. Then Sarah meets a mysterious man with an ambiguous accent, a suspiciously bare apartment, and a lockbox full of weapons. He's a spy, and he needs Sarah to become one, too, to pull off a mission he can't attempt on his own: infiltrate a boarding school attended by the daughters of top Nazi brass, befriend the daughter of a key scientist, and steal the blueprints to a bomb that could destroy the cities of Western Europe. With years of training from her actress mother in the art of impersonation, Sarah thinks she's ready. But nothing prepares her for her cutthroat schoolmates, and soon she finds herself in a battle for survival unlike any she'd ever imagined.

Brutal and cunning, what a brilliant book.

After hearing a lot about Orphan Monster Spy by Matt Killeen on Twitter, I knew I wanted to read it. Needless to say, I am BLOWN AWAY with how incredible this book is.  What a brilliantly brutal and stunning story. I have not read too much historical fiction books, but god I want more. There was not a dull moment within Orphan Monster Spy. Fast-paced and the characters brought so much to the book.

The story follows 15-year old Jewish girl Sarah. She is left alone after the traumatic death of her mother. On the run, she soon finds herself alongside a man who later is known as Captain. She is then sent to a boarding school in Nazi Germany to befriend a girl called Esla. This girl may hold information about a man who threatens Europe.  Throughout her investigation, however, she suffers many troubling moments which leaves her on the brink of death.

The historical fiction aspect of Orphan Monster Spy is super gripping. Getting to see the dark moments during the Holocaust and seeing into the mind of the Nazis. Seeing this woven into the book gives a sense of what times were like back then. Reading about this time period really shows how much Killeen put into the plot and his knowledge/research is top-notch.


Sarah is FIERCE. Her character in Orphan Monster Spy is so bloody good. She is the most fierce and badass and wonderfully resourceful character. Sarah is definitely a character that you want to read about. I also loved the moments that we get to see her most haunting memories and is willing to go on. Even though she gets thrown into a pit filled with lions, she comes out on top. Even during all the trauma and memories, she is strong.

I also really enjoyed the Captain and the relationship between him and Sarah. I loved how the Captain ended up being a “parent” of a sort to her and how he cared for her through everything. He was mysterious and holds many secrets and I enjoyed learning about him more. Their relationship was really heartwarming.

When it comes to side characters in Orphan Monster Spy, I thought Mauser was super cute, albeit quiet. But I felt so strongly for her. Mauser, or “MOUSE”, is picked on a lot and she made me feel super sad. But she is a great side character.

A bit too much at times, but god it is so good

Orphan Monster Spy is a very brutal book. Don’t start reading this book if you are not prepared for a brutally hitting story. It really is one that will punch you in the face over and over. At points, you may even think it’s too much. However, it REALLY IS SUCH A GOOD BOOK.

This book holds so many twists and turns, fast-paced action and moments that have you on the edge of your seat.
