Seventeen-year-old Aderyn ("Ryn") only cares about two things: her family, and her family's graveyard. And right now, both are in dire straits. Since the death of their parents, Ryn and her siblings have been scraping together a meager existence as gravediggers in the remote village of Colbren, which sits at the foot of a harsh and deadly mountain range that was once home to the fae. The problem with being a gravedigger in Colbren, though, is that the dead don't always stay dead. The risen corpses are known as "bone houses," and legend says that they're the result of a decades-old curse. When Ellis, an apprentice mapmaker with a mysterious past, arrives in town, the bone houses attack with new ferocity. What is it that draws them near? And more importantly, how can they be stopped for good? Together, Ellis and Ryn embark on a journey that will take them deep into the heart of the mountains, where they will have to face both the curse and the long-hidden truths about themselves.
