High Treason — Sean McFate; Bret Witter

In this pulse-pounding third action thriller for fans of Brad Thor and David Baldacci, hero Tom Locke, introduced in Shadow War and Deep Black, must stop traitors and ruthless mercenaries working together to overthrow the president.

En route to the National Prayer Breakfast, the U.S. vice president's motorcade is hit in a vicious, expertly planned attack that throws Washington, D.C. into chaos. Everyone assumes it's ISIS -- everyone but young FBI agent Jennifer Lin. She is certain that Russia is behind the strike.

Half a world away, military contractor Tom Locke has his own doubts about what happened -- and who did it. He suspects his former employer, Apollo Outcomes, might be involved. But why would the global security firm orchestrate an attack on US soil?

Returning to D.C., Locke discovers that a civil war has fractured Apollo. A division has splintered off, a rogue unit led by an ambitious, unprincipled former colleague who may have planned the attack himself. But Apollo couldn't have pulled this off without help from inside the government. The official's itinerary and route were confidential -- which means there must be a traitor high up in either the White House or the NSA who is leaking information to Apollo.

But why? And who could be pulling the strings? Islamic fundamentalist terrorists? Or is this a new ploy by Putin to discredit the U.S. government and divide it from its democratic allies? Only Locke can get to the bottom of the conspiracy that traverses the globe and blow it apart with one strategic strike before it's too late.
