From New York Times bestselling authors Andrews & Wilson, The Adversary is the next heart-stopping installment in the Tier One series. 

For John Dempsey, it’s a time of uncertainty.  

As a new administration tries to piece together who was behind the assassination of an American president, task force Ember is a team without a target. Newly Minted POTUS, Kelso Jarvis, is haunted by strange dreams of a house on fire, and Dempsey’s son Jake—who has begun his own journey as a SEAL—can’t escape the ghost of the father he believes to be dead.  

But when a routine intelligence gathering mission in Taiwan goes horribly wrong and one of Ember’s own is captured, Dempsey’s frustration only grows. As Ember races to rescue their teammate before it’s too late, three of America’s strongest warriors—Dempsey, Jarvis, and Jake—must ask themselves if tomorrow’s adversary resides across the Taiwan Strait, or within themselves.
