His Pet Wears A Thorn Crown

Della is sold to the manor owner Rowan, a perfect - looking ancient tree demon, due to her father's debt. Forced to wear a living thorn collar, she becomes a low - level 'gardener' in the manor, suffering torture and humiliation. She discovers a silver tree that can break the bondage, not knowing it's connected to Rowan's heart and that Rowan has a deeper cage behind his coldness.
