Where Shadows Bloom takes place in Ravenglade, a fortified stronghold pressed between two overlapping Dead Zones. The town is home to stubborn, resilient people who refuse to abandon their land. Rangers, Noctorians, and wanderers live side by side, holding back the Black Forest's encroaching horrors. Alex Harkon is twenty-three, half human and half Sombrith, born of shadow and sharpened by survival. Her body holds exceptional healing, heightened strength, keen senses, and a speed that keeps her alive when the forest hungers. She earns her coin as the hunter for The Velvet Vial, the apothecary at the heart of Ravenglade.

Its mistress, Lady Bellara Vex, is an exiled Lothari sorceress with silver eyes and an unsettling calm. She sends Alex to retrieve rare ingredients from places where most hunters never return. Between perilous hunts and the soft pull of whispered desires, Alex walks a line as thin as a serpent's trail. Dewdrop, her loyal snake, becomes a living symbol of the choices she must make. In the dance between Bellara's quiet, mesmerising influence and Alex's own flickering loyalties, family is not just inherited but chosen. Ravenglade's fate may rest on whether Alex becomes a loyal blade, a defiant force, or a lover bound by the coils of a bond older than either light or dark, something far more tangled and serpentine.
