Perfect for you if...

You love Korean mythology woven into contemporary settings and want something fresher than typical paranormal romance.
You're drawn to slow-burn chemistry between characters with genuine history and unresolved feelings.
You enjoy fantasy stakes that escalate beyond the romantic plot to genuinely threaten the wider world.

Maybe not for you if...

You prefer standalone books, as this is book one of a series with cliffhanger elements.
You want romance to be the full focus. The mythology and world-building are equally weighted with the relationship.
You're looking for high-action pacing throughout. The opening half is deliberately quieter as Sunny processes her past.

About this book

Sunny Cho is a nine-tailed fox spirit who has spent years drifting between cities, suppressing her fox nature and powers to live an unremarkable life. When Ethan Lee, a private investigator and friend she abandoned eight years ago, tracks her down and asks for her help solving his brother's murder, her carefully constructed isolation begins to unravel. As Sunny and Ethan investigate, they discover their quest extends far beyond vengeance, drawing them into both the mortal realm and the world of gods. An ancient evil is awakening, and Sunny must confront an impossible choice: prevent the destruction of multiple worlds or accept a love written in the heavens. The novel blends Korean folklore with modern American settings.
