Her Soul

Ray was used to seeing the world through the lens of a camera, capturing ancient evil from the fog. But when the shadows begin their hunt, her only chance of salvation becomes Leon — a dangerous demon who has regarded humans as mere toys for centuries.
He is the guardian of the cursed city and its chief executioner. A predator who never knew attachment until he met her, whose fearlessness made him freeze in anticipation. Now Ray is no longer just a victim for him. She is his only treasure.
For her, Leon is willing to break the rules of his own hunt and confront the hidden world. In this survival race, passion becomes the only weapon, and the monster's hands are the safest place on earth.

1. Scorching chemistry and the 'monster-protector' trope. The relationship between Ray and Leon is an explosive mixture of primal passion, obsession, and loyalty.
2. An atmosphere where gothic surroundings and the whisper of the abyss create a perfect backdrop for the most candid romance, which has impressed BookTok.
3. Lovecraft through the lens of Guillermo del Toro.
4. A TikTok phenomenon with 60 million views that topped the Amazon charts.
