The Buried and the Bound is the first book of Rochelle Hassan's YA dark fantasy trilogy, set in Blackthorn, Massachusetts. Aziza El-Amin is the town's only hedgewitch, and the boundary between the human world and fairyland is hers to keep. When something dark wakes in the forest and begins eroding that boundary, the work outgrows her.
Leo Merritt has his own magical wreckage. On his sixteenth birthday a dormant curse took every memory of his true love, and a year of asking questions has got him nowhere. He and Aziza strike a bargain: he backs her up on her nightly patrols, she helps him break the curse. Meanwhile Tristan, contracted to a cruel and powerful hag, is looking for an exit that does not cost the people he loves.
When the thing in the woods turns toward the three of them, their survival depends on a necromancer none of them are sure they can trust. Hassan writes fae magic with teeth, and the book is as much about what the three owe each other as it is about the creature in the trees.
