Bad Graces by Kyrie McCauley

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.
