As the only hedgewitch in Blackthorn, Massachusetts, Aziza El-Amin has bargained with wood nymphs, rescued palm-sized fairies from house cats, banished flesh-eating shadows from the local park. But when a dark entity awakens in the nearby forest, eroding fairylands boundary, run-of-the-mill fae mischief turns into outright aggression, and the danger becomes too great for her to handle alone. She is forced to seek help from two unlikely allies: Leo, a boy who was cursed to forget his true love and isn't afraid to risk his life looking for answers; and Tristan, a mysterious young necromancer she's not certain she can trust. Theyll have to work together to eradicate the new threat and take back their hometown . . . even if it forces them to uncover deeply buried secrets and make devastating sacrifices.
