In the quiet village of Greythorne, fear of the surrounding forest is treated as a matter of simple survival. The locals know the rules: keep a hand on iron, never answer singing after sunset, and do not follow the lights into Morrowdeep.Catherine Mitchell is a practical healer who deals in stitched skin and pine pitch, not superstition. But when a local hunter arrives at her table with a shredded leg, his wounds tell a story he refuses to speak. The flesh is struck with unnatural frostbite despite the spring rain, and deep within the torn muscle lies strange, glowing silver dust that freezes Catherine's steel needle.As she investigates the claw-like tracks, Catherine uncovers a chilling truth: the dangerous magic of Morrowdeep is no longer keeping to the shadows. Something ancient has bled into Greythorne, and ignoring the terror will no longer keep them safe.
