Shadow War — Sean McFate; Bret Witter

Tom Locke is an elite warrior working for Apollo Outcomes, a very successful private contracting firm. He is tapped for a top-secret black op in Ukraine, and has one week to rescue an oligarch's family and pull off a spectacular assault.

What Locke doesn't know is that Brad Winters, his ambitious and enigmatic boss, is engaged in a high-stakes geopolitical chess game with influential powerbrokers in capitals around the world. One misstep could cost them everything. And that misstep may already have been committed by Locke's former love, war correspondent Alie MacFarlane, who impulsively makes a move that risks both their lives.

Now Locke must move quickly to stay ahead of a looming betrayal that could lead to catastrophe…and tip the balance of power toward Putin's Russia.
