About The Book

The Addams Family meets Nancy Drew in this delightfully spooky illustrated middle grade mystery following a young human girl determined to protect her monster foster family from discovery.

The first rule of the Monstrous League of Monsters is to keep monsters hidden from humans. But when zombie George and his cat companion Bandit find an abandoned human baby, they can’t leave her to be eaten by hobgoblins. So they spirit her home where she quickly becomes part of the family.

Fast-forward ten years, and young Theodora doesn’t seem too scarred by her monstrous upbringing. But a series of anonymous letters suggests that someone is about to reveal the secret of her caretakers’ identity. If Theodora doesn’t act fact, she may lose her beloved monster family forever.

Raves and Reviews

Readers will be irresistibly drawn into the captivating world of Kopy's monster-filled middle-grade novel, where the promise of tantalizing secrets sets the stage for adventure. Through the snarky, charming narrative of an mysterious observer, the story unveils a delightful blend of whimsy and mystery revealing truths that adults often keep hidden from children—namely, the existence of monsters. Rescued as a baby from a graveyard, Theodora grows up in a house full of monsters learning to be good, but they have to keep her a secret. That's easier said than done, especially when Theodora starts attending school with an unusually terrible head teacher and someone is threatening to report her monster family for breaking the no-humans rule. Alongside the lively characters and light mystery, the narrator imparts a particularly mischievous charm, with cheeky asides about how to prank teachers and the many ways parents are wrong. With playful, comical illustrations reminiscent of the Addams Family that vividly bring the scenes and characters to life, this delightful, cheeky romp is ideal for those who relish eerie tales with a humorous twist.
