When seventeen-year-old Anna is thrown into the Unity Experiment?an ongoing team building exercise to promote unity between warring species?she begins to unwittingly retrace the fatal steps her father took a decade ago. But she quickly discovers she is the only one within the experiment able to communicate with the spirit world.

This revelation ignites her curiosity and her focus shifts from surviving the experiment to finding out the truth behind her father's death. But this power comes at a cost, and she becomes the prime target of the other teams who covet this link wanting answers from their dead.

If Anna can master this unusual skill, she'll be able to bring together species who currently have nothing but contempt for each other. Of course, she'll have to avoid being killed by everything and everyone around her. If she can't, she'll never have the chance to unveil the secrets the human government never wanted unearthed in the first place. Too bad they didn't count on a 17-year-old who can hear the dead to shake things up.
