When someone tries to kill Riley O'Connor in the nation's capital, her good friend in California tells her to come home. But she's not a quitter; she is determined to find the truth about a friend who was murdered. The answer is hiding in the middle of a conspiracy involving a Russian oligarch and a web of shadowy figures who have worked their way into the FBI and even the White House. It comes down to the last 24 hours, and how good O'Connor and Jack Beckett are at staying one step ahead of the bad guys. Truth and justice depend on it.
