Forbidden Bite, An Enchanted Mates Romance

Why these tropes fit

After ten years away hunting evil, werewolf Callum Mackintosh returns to the small town of Mercy suffering from an ancient werewolf disease that only one person can cure: Adelaide Webb, the witch he broke the heart of a decade ago. Adelaide runs a successful plant nursery and is surrounded by her loving parents and five older brothers, but Callum reenters her life as a painful thorn. As Callum earns her trust and confesses his intent to stay, an evil spirit rooted deep in the earth begins targeting Adelaide, sprouting poisonous weeds around her nursery and causing vertigo-like symptoms to threaten her safety. The spirit feeds on Adelaide's power and will stop at nothing to keep the enchanted, fated mates apart, forcing Adelaide to choose between silencing her magic to survive or trusting that true love will conquer the darkness.
