After seven long years, Joan Greenwood has been called home. As the only one in her elite family of witches who cannot manipulate magic, her return to New York City is lukewarm at best. But it's upended by the disastrous news that someone has created a spell that can turn an unmagical human into a powerful witch.

While her family covets the ability to create a new generation of witches, Joan is wary of such power in the hands of her conniving relatives. When her best friend - who happens to be a vampire - confesses he has secretly, accidentally, saved this human-turned-witch from an uncertain fate, Joan is thrust headfirst into a desperate race to undo the spell before it kills its unwilling host. But as the different factions of the magic world hunt Joan across the city, she gathers a new family of allies to help her.

Soon, her race to the truth draws her deeper into the heart of the city's magic, through uncertain alliances with a (very attractive) family rival, and far beyond the limits of everything she thought her own magic was capable of. Only now does Joan see... her power could rewrite the rules of the magic world-or bring the entire city to its knees.

This debut contemporary fantasy features a lovable cast of queer, BIPOC characters, witty writing, and a sapphic slow-burn romance, An Unlikely Coven is perfect for fans of A Discovery of Witches, An Unkindness of Magicians, and The Very Secret Society of Irregular Witches.
