Terror once again stalks the City of Brotherly Love, raising its head in the most unlikely of places: a kids' chess tournament.
Philly PI Paige Harmon doesn't know much about queens and rooks, but she is there to support a prodigy who has already been haunted by violence. When shots ring out, Paige will do whatever it takes to protect her young friend.
Evil does not stop there, and Paige soon finds herself in the middle of a conspiracy with an international reach fueled by generations of hatred. Innocent lives hang in the balance, but political alliances prevent the FBI from fully sharing their resources. Paige knows she can count on Andie June, a woman used to dealing with those who hide in the shadows. Together they will need all of their skills to avoid being pawns in a game of murder, moving ever forward to their doom.
