Four years ago, a beautiful young heiress survived an attack that claimed the lives of both of her parents. The crime made headlines all over Los Angeles, both for the vicious nature of the killings and the seemingly random nature of the attack: nothing was stolen, and the van Aust family had no obvious enemies. Melia van Aust fled the city soon after the murders - which were never solved - but her brother Jasper has not been seen since.

After a childhood spent in the shadow of her famous parents, Rainey Hall understands the dynamics of a dysfunctional family. She still hasn't recovered from a tragedy that tore her own family apart six years before. It's part of the reason why she started her own private investigation agency-to aid victims of crimes that might otherwise go unsolved.

When Melia returns to Los Angeles and moves back into her family home, someone begins sending her increasingly violent messages that allude to the killing of her parents. She hires Rainey to track down the culprit and find her missing brother. Touched by the similarities between their lives, Rainey feels compelled to protect Melia, even when it becomes clear that their relationship has become more than professional.

Soon, Rainey finds herself falling down the rabbit hole of Melia's life. Her quest to find Melia's stalker will bring her in contact with disgraced royals, seedy neighbors, violent ex-boyfriends and former staff, each one with their own set of secrets. As the threats against Melia escalate and the two women are drawn together, it's only a matter of time before another victim turns up.
