Liv Whitlock knows she doesn’t belong there. But after years of stumbling between foster homes, often due to her own self-destructive tendencies, Liv desperately needs to change the trajectory of her life . . . so she steals her perfect sister’s identity.

Liv starts to rewrite her story, winning a prestigious internship on a movie set filming in Alaska, and finds herself on a luxury yacht alongside pop star Paris Grace, actress sisters Effie and Miri Knight, Olympic gymnast Rosalind Torres, and social media influencer Celia Jones. Liv tries to find common ground with her famous companions, but just as the group starts to bond, a violent storm wrecks their vessel, stranding them on an island in the North Pacific Ocean.

Among the threats of starvation and exposure, they learn there is a predator lurking in the forest, unlike anything they’ve seen before—until they begin to see it in themselves. Every injury they suffer on the island causes inexplicable changes in their bodies. With little hope for rescue and only each other as their final tether to humanity, can the girls endure the ominous forces at work on the island? Or will they lose themselves to their darker natures?
