Kenneth Rowe's ordinary life as a young omega wolf was about to take an eventful turn when he unexpectedly mates with an unknown Lycan on a night of a full moon. Learning a month later that he is with a child and that the supposed mystery father was actually the youngest son of a pureblood Lycan family that runs their town -- Ethan Wallace, Kenneth knew for sure that he was in a heap of trouble. With the contrast in their life status and the never ending discrimination of pure-blooded Lycans towards wolves, Kenneth also learns that his baby may be the reincarnation of a mythical monster that would cause chaos and destruction to the world called in ancient text as the Blood Enigma.

Eighteen people arrive at a remote mountain lodge - couples, friends, strangers- each drawn by different reasons: a vacation, a retreat, a break from life. None of them realize they've been lured there by something deeper than coincidence. Something ancient. Something waiting. As a snowstorm seals them in, unsettling events begin to unravel their reality. Hallucinations. Shifting memories. Sudden violence. The lodge becomes a trap, and one by one, they begin to fall - victims of forces none of them can explain. But this isn't the first time. Though they don't remember it, they've all been here before. In other lives. Other versions of themselves. And each time, the outcome is the same. There is a reason they keep coming back.

Leander Holt, a wealthy, acclaimed author, lives in the shadow of grief and guilt. Once married, now estranged from his wife and daughter, he is still haunted by the childhood disappearance of his younger brother, Luca, during a family trip to the snowy mountains. His parents never forgave him for being the one who returned, and Leander has never forgiven himself either. When his friends, popular streamers, stumble upon a malnourished man in the basement of an abandoned house, they believe they've rescued a long-lost victim. But when Leander sees the man in the hospital, he realizes with shock - it's his missing brother, Luca. Elated, he brings him home, blind to the unsettling strangeness in Luca's eyes, movements, and silence. What follows is not a reunion, but the unearthing of a nightmare.
