It's presidential primary season in Washington, DC, and both parties are on edge. At campaign rallies for all the candidates around the country, there are disturbing incidents of violence and protest and shocking acts of civil disobedience. Rena and Brooks are happy to sit it out.
Against this backdrop, Wendy Upton, the highly respected centrist senator, must make a choice: she's been offered the VP slot by both parties' leading candidates. When she receives an anonymous, unnerving threat that could destroy her promising career, she hires Peter Rena to investigate her past and figure out which side is threatening her and what they are threatening her with.
As Rena digs through the senator's seemingly squeaky-clean past, he must walk the tightrope between two parties at war with each other and with themselves, an electorate that is as restive as it has ever been, and a political culture that is as much driven by money as it is by ideology.
