Destiny brings Leah Barton, USA director of Prisoners of Conscience International, and Fr. Javier de Cordova together again after 14 years. Santo Sangre's President, Raul Montenegro, has lured the priest into a devious diplomatic mission to meet with POCI's leaders and plead his country's innocence. Javier agrees to represent the man he despises, because it will give him one last opportunity to see the woman he once loved. Javier doesn't know that Montenegro has involved him in an assassination plot that includes Leah's son. Unexpectedly, these star-crossed lovers discover that the spark of their former love still lives within them. Once Javier connects the dots and learns the truth about the scheme, he and Leah must find a way—if one exists—to thwart their invisible assassin.
