A year after her sister's death, Katey Philips receives an anonymous letter. The message suggests her sister did not die by accident on the night she hosted a work party. Disguising her identity, Katey moves across the country to work at the public relations firm that employed her sister.
Katey quickly learns she doesn't work at an ordinary PR firm. The company runs a second line of business her sister never spoke of. This secret work is dangerous and shameful and participating in it is the only way Katey can uncover what happened to her sister. Katey must choose how far she will go to find the truth, even if it means sharing the same fate as her sister.
