The best YA books about secret spy schools for girls

Why am I passionate about this?

Spy stories have always captivated me. This fascination grew after I learned that throughout history, many women worked behind the scenes as key spies. How cool is that? So, I decided to write a girls' spy school set in Jane Austen's world. Junior Library Guild said this about A School for Unusual Girls, “An outstanding alternative history series entry and a must-have for teen libraries.” Scholastic licensed the series for their school book fairs. Ian Bryce, the producer of Spiderman, Transformers, Saving Private Ryan, and other blockbusters, optioned it for film. To date, more than 600,000 copies of my award-winning historical novels are in the hands of readers around the globe.

What is my book about?

A secret spy school set amidst Jane Austen’s high society.

Stranje House is one of Regency England’s dark little secrets—daughters of the beau monde who don't fit society's constrictive mold are banished to Stranje House to be reformed into marriageable young ladies. Or so their parents think. In truth, headmistress, Emma Stranje, has plans for these young ladies—plans that entangle the girls in the dangerous world of spies and diplomacy in the Napoleonic war.

The books I picked & why

Book cover of Harriet the Spy

Kathleen Baldwin Why did I love this book?

Harriet the Spy was one of my favorite books as a child. Although Harriet wasn’t actually attending a spy school, she was training to be a spy so she could become a writer. She observed her neighbors and friends with brutal honesty. In the end, she learned that she needed to temper her observations with kindness. This story touched me deeply. For years, I ate tomato sandwiches in honor of my beloved Harriet, and I hauled that book around with me until my copy became so tattered and worn it was unreadable.

Book cover of A Spy in the House

Kathleen Baldwin Why did I love this book?

I absolutely loved this series! The heroine is a young woman struggling to survive the harsh streets of Victorian England. Caught stealing, Mary Quinn is convicted and sentenced to hang. However, the Agency rescues her from the noose and provides her with an education. In return, she trains to work as an investigative agent among the upper-class society of London. These books expose the realistic darker side of that world, but if you could handle Oliver Twist, you can handle these. Lee captured the mystery and intrigue so brilliantly I could not put them down.

Book cover of I'd Tell You I Love You, But Then I'd Have to Kill You

Kathleen Baldwin Why did I love this book?

This delightful series is so much fun it rates a 'must have' on my list of girls' spy schools. The spy school is housed in a charming old mansion, complete with secret passages and hidden elevators. It is attended by carefully-selected, super-smart young women who train to become the Gallagher girls—spies extraordinaire. Naturally, there is a counterpart boys’ spy school. With a touch of romantic angst, this series does not disappoint. The girls are each distinct, memorable, and tons of fun.

What is this book about?

Gallagher Academy might claim to be a school for geniuses - but it's really a school for spies. Cammie Morgan is fluent in fourteen languages and capable of killing a man in seven different ways (three of which involve a piece of uncooked spaghetti). But the one thing the Gallagher Academy hasn't prepared her for is what to do when she falls for an ordinary boy who thinks she's an ordinary girl.

Sure, she can tap his phone, hack into his computer, and track him through a mall without his ever being the wiser, but can Cammie have a normal…


Book cover of Grave Mercy

Kathleen Baldwin Why did I love this book?

Admittedly, this is more of a school for assassins, but they’re also spies training at a nunnery in ancient Brittany. The medieval setting feels authentic and fascinating. The plot is a little darker, especially in the beginning, but masterfully written. And I fell in love with the characters. Reading these books, I felt as if I was there, experiencing every scene, living through every action, and I can still remember years later. That’s great storytelling!

Book cover of Etiquette & Espionage

Kathleen Baldwin Why did I love this book?

I cannot resist Gail Carriger’s tongue-in-cheek writing style. If you enjoy quippy hilarious steampunk, don’t miss Etiquette & Espionage. It is a finishing school for young ladies set amid a Victorian world peopled with vampires, werewolves (some nice and some not so nice), cute cuddly mechanimals, and evil automatons. While these young ladies are being trained in the “art of dance, dress, and etiquette, they also learn to deal out death, diversion, and espionage—in the politest possible ways, of course.” It is a hoot and a half! Carriger writes Victoriana as no one else can.

It's one thing to learn to curtsy properly. It's quite another to learn to curtsy and throw a knife at the same time. Welcome to finishing school.

Sophronia is a great trial to her poor mother. Sophronia is more interested in dismantling clocks and climbing trees than proper manners-and the family can only hope that company never sees her atrocious curtsy. Mrs. Temminnick is desperate for her daughter to become a proper lady. So she enrolls Sophronia in Mademoiselle Geraldine's Finishing Academy for Young Ladies of Quality.

But Sophronia soon realizes the school is not quite what her mother might…
