At the prestigious Deighton Academy, Astrid's life is defined by a secret—a burgeoning magical power she struggles to control. In spite of trying to keep her head down, it's not long before she draws the attention of the most feared girls in school: Selena, Rosemary, and Lilith.

In spite of all the warnings, she's drawn into their world of dark magic and ancient rituals, and learned of their ultimate goal; to unleash a forgotten goddess for the chance at ultimate power.

As Astrid delves deeper into the group and her magical studies, she soon uncovers a chilling truth: the greatest threat isn't the ancient deity they are trying to summon, but the volatile rivalries festering within her new coven.

Friendships twist into bitter betrayals, and the lines between ally and enemy blur, leaving Astrid isolated and uncertain of who she can trust. 

Astrid must fight to master her formidable magic on her own terms, and harness her powers to expose the betrayal at the coven's core.

Perfect for fans of The Craft, The Chilling Adventures of Sabrina, and Dead Poet's Society, The Moon is a Door is a thrilling tale of forbidden magic, treacherous bonds, and the dark heart of ambition.
