While enjoying the benefits of wealth and proximity to the novel's attractive male characters, she faces a growing threat from a mysterious and calculating antagonist. What was once a superficial character becomes a real danger to Ruby's safety. She must find a way to counter his schemes, or risk the story ending in disaster.
