Vivienne only meant to follow the young gentleman until she could steal her locket back. She never meant to strand them on the moor and she certainly never meant to use her power in front of him—but that was before they were faced with a situation where revealing her secret means the difference between life or death.

The last thing Will needs on his first monster-hunting quest is a ragged petticoat tagging along. Now he’s responsible for this street girl’s safety while he hunts the mysterious creatures prowling the moor and tries to prove—to himself most of all—that despite his deadly power there’s goodness in his soul.

With the portal to safety closed, can they trust each other enough to share their secrets—and survive?

It seemed like a sensible plan at the time: bring the girl home, build up her strength, then send her on her way as quickly as possible—but then he accidentally introduced her as his long-lost cousin. Now he has to juggle his disapproving housekeeper, guest-turned-counterfeit cousin, and rumors of a strange man haunting the manor grounds.

Vivienne knows none of it is permanent: the clean clothing, spacious rooms, good food—and especially the role she finds herself playing as Will’s cousin. Recharged by the tropical sun of a secluded beach she’s determined to leave the instant she’s strong enough—especially after Will accuses her of being in league with his mysterious enemy.

Will the beach that restored her health now threaten both of their lives?

Vivienne seems to be the continued target of strange attacks as she navigates an unexpected friendship with a young woman who shares her own unnatural power.

Will, though encouraged by his mentor to leave on another secret mission, is determined to stay and keep Vivienne safe—even if that means tolerating the presence of Tom, his housekeeper's mischievous, portal-hopping nephew who insists on being the friend Will never asked for.

When Tom helps Vivienne open her locket and Will discovers his great-grandfather's ledger, they may finally hold the keys to their families' unnatural legacies—if they survive their mysterious enemy's attempt to forcibly reveal their secrets to the entire village.

Clues from the past could provide hope for the future—but can they overcome the challenges of the present?
