When Agatha Harkness finds herself yanked out of her mysterious past and plopped in a modern-day high school, the race is on to find the key to saving her coven while discovering first love and battling an ancient foe. Agatha Harkness is a powerful witch stuck living amongst an untalented group of witches in 1690s Salem, Massachusetts. That’s all right—the dreary coven meetings and fake herbal potions will all be worth it once she finally gets her hands on one of the most magical artifacts in the Darkhold, a book of extraordinary power. But just as it’s within her grasp, disaster strikes the coven! Agatha is about to reluctantly save the day when she is rebuffed by the nosy, stuck-up Martha. Now, thanks to the interference, Martha, Agatha, and the Darkhold have been unceremoniously dropped in one of the most terrifying locations a witch has ever encountered—modern-day high school. Armed with just her smarts and her spells, Agatha embarks on a quest to recover the Darkhold and an incognito Martha. Along the way, she encounters a meddlesome crow, a potential first crush, and a new coven. She almost starts to feel like she’s found her home, until Martha returns from the shadows—this time with dire consequences.
