The Grimoire Grammar School Parent Teacher Association

From the NYT-bestselling author of Dreadful, Big Little Lies goes to magic school, cozy fantasy perfect for fans of T. Kingfisher, Olivia Atwater and Heather Fawcett. Featuring orange sprayed and stencilled edges, with magic symbols, unicorns and baked goods from the book.

Two parents and their recently-bitten-werewolf daughter try to fit into a privileged New England society of magic aristocracy. But deadly terrors await them – ancient prophecies, remorseless magical trials, hidden conspiracies and the PTA bake sale.


When Vivian’s kindergartner, Aria, gets bitten by a werewolf, she is rapidly inducted into the hidden community of magical schools. Reeling from their sudden move, Vivian finds herself having to pick the right sacrificial dagger for Aria, keep stocked up on chew toys, and play PTA politics with sirens and chthonic nymphs and people who literally can set her hair on fire. 

As Vivian careens from hellhounds in the school corridors to demons at the talent show, she races to keep up with all the arcane secrets of her new society—shops only accessible by magic portal, the brutal Trials to enter high school, and the eternal inferno that is the parents’ WhatsApp group. 

And looming over everything is a prophecy of doom that sounds suspiciously like it’s about Aria. Vivian might be facing the end of days, just as soon as she can get her daughter dressed and out of the door…

A very fun read, and perfect for the Halloween/Samhain season if you're in the mood for a cozy fantasy. I loved the imaginative world-building and magical setting, but what really stood out were the relatable moments, like Aria’s parents dealing with a snooty PTA and the challenges of introducing your child to a new school system. Beneath the humor and whimsy, the story beautifully explores themes of family, belonging, and forging friendships in unexpected places.

This is the first “cozy” fantasy novel I’ve read and I quite like the genre! The main character, Vivian, was relatable — everyone has felt excluded or struggled to fit in at some point in their life — and I enjoyed her character growth from self-depreciating, guilt-ridden parent to a confident and courageous werewolf mom. My one minor critique is that the villainess, Moira, felt somewhat underdeveloped and one-dimensional. Moira and Vivian were good friends, so I would have liked to see Moira grapple with the guilt of using Vivian/Aria as a scapegoat to get her son into his dream high school; particularly, in the scenes where Moira attacks Vivian at field day and when they meet for “closure” at Starbucks.
