Cost of Honor (Honor, #10)

Secret Service Agent Oakes Weaver is in the midst of the biggest assignment of her career—leading the advance team for President Andrew Powell’s impending trip to Philadelphia where everyone expects he will be nominated to run for a second term. The last thing she needs is a tragedy among the president's inner circle that might not be an accident, or the sudden recruitment of Ari Rostof, a woman who might be a lot more than she seems. But Oakes doesn't get a say in policy. She only has to secure the president’s safety—at all costs.

First Daughter Blair Powell and her spouse, Cameron Roberts, are among the reelection campaign members accompanying President Andrew Powell to Philadelphia. While the president may be protected by his Secret Service agents, those close to him are literally in the kill zone, and his adversaries will stop at nothing to further their cause—even mass murder.
