Three girls battle a dangerous secret society that will do anything to protect an ancient Greek power in this murder mystery for fans of Dan Brown.

In ancient Rome, it was whispered that the great philosopher Plotinus could project his soul into another human being in a ritual that hinged on a kiss.

In present-day Delphi, California, the sole remaining guardians of the Plotinus Ability hide in plain sight as members of the exclusive Oculus Society-until their leader, Octavia Harris, is killed in her own home. With no leads on the case, Octavia's daughter, Gretchen, vows to find her mother's murderer at any cost.

One piece of the puzzle falls into place when Gretchen's best friend, Jessica Shaw, discovers the Plotinus Ability. Skeptical but curious, the two can't resist trying the ritual, but they're not alone. Ariel Miller, an outsider with a well-known hatred of all things Oculus Society, films the friends exchanging their first kiss, and it isn't long before the YouTube video ("Popular Girls = Secret Lovers") goes viral. As Ariel's guilt and the girls' suspicions of her mount, the three must forget the past and trust one another if they are to find the murderer still in their midst.
