The only clue she has is a letter detailing that Amelia has been working as an upstairs girl in a club owned by two handsome men, Eli Masters and Jason Braddock. However, when Avilon arrives at the club, the only way she can get to talk to them is by auditioning for the singing position, and she captivates them with her beautiful operatic voice.

As she grows closer to Eli and Jason, the search for her sister unleashes the wrath of a madman bent on revenge, threatening to destroy everything and everyone she's come to love.
