A critical mission requires a deadly operative... Mercury Cale is as brilliant as she is lethal. When they call her, it's because the world is about to go down in flames. In the sweltering heat of the Nicaraguan jungle, a CIA plane crashes, leaving no survivors. Amid the wreckage is a black case containing a dark secret... one that, in the wrong hands, will cause bloodshed in the Middle East on a scale never seen before. The private contractor sent in to retrieve the briefcase is executed. Mercury and her crew are now locked into an urgent, dangerous hunt for the case and assassins, working completely off the books. From the jetsetting French Riviera to Central America, Mercury reluctantly teams up with the contractor's son, Owen Wright. The former British soldier is determined to avenge his father's death and possesses skills Mercury could use. They're outnumbered and outgunned... but Mercury Cale will not be outmaneuvered. Fans of Atomic Blonde, Nikita and Alias will love Critical Salvage.
