Every monster tracker around knows you call on Dr. Stella Pike if you need a wound patched, a hex reversed, and a magically protected place to crash. Her home, Eight-Fold Acres, has long been a haven for trackers in need of a sanctuary from life on the road. When the sons of her sworn enemy-the long-ago banished Hills-show up at her doorstep, Dr. Pike almost breaks her solemn vow to do no harm.

But the unwelcome Hill brothers are soon the least of her problems. An oily, tempting magic has breached the impenetrable barriers that protect her family's sacred land...and has targeted Stella. Staying alive means fleeing the only place she's ever felt safe. And while she doesn't trust the Hill brothers as far as she can toss a troll, going on the run with them is the only way to discover the truth. Relying on her wits, her knives, and with the traitors at her side, Stella must seek answers from the very evil that's coming for her. An evil that feels familiar, compelling.

Evil that calls her home.
