Her boss had black wings

A fae romance in modern Los Angeles, with a billionaire boss, a fake engagement and a family that is not human. Claire Mitchell needs the job to pay her rent. On the day of her interview, the elevator lights go out and, for one second, she sees enormous dark wings behind the man beside her. Then she faints. The man is Arthur Castellan, the CEO, and he hires her before she even finishes the interview. Two years later, his father has arranged his marriage to a fae woman from the kingdom of Vanora. To escape it, Arthur says he is already engaged. Now he has seven days to bring a fiancée to dinner, and he asks Claire. What he still has not told her is why it has to be her.
