It's been a couple years since Commander John Marion - the US Navy's most decorated SEAL - hung up his dog tags, choosing his cherished Alpha over war.
Call and Alpha have settled comfortably into their carefree lives nestled in the mountains of South Carolina. No more combat for the Commander and no more ordered killings for the deadliest assassin in the world.
However, nothing stays peaceful forever.
When Alpha's brother Omega comes to their secluded home with a distressing message from their Order, Alpha has to answer the call. But what neither of them expect is for the Order to send them a new assassin, one just as deadly as both of them, to seek their counsel and bring them back Persia.
Lion's commanding presence was not at all what any of them anticipated. Especially Omega. Lion realizes what Omega is to him right away, but the stubborn man fights his every advance. Lion knows he and Omega have to connect if they're going to be victorious. He was sent to bring back an army but if he can't get his cherished to yield to him, they are sure to fail.
Call refuses to let Alpha fight a gang of rebel assassins without him. Omega will fight by his brother's side, no matter what... and Hawk saw them coming for his help before anyone else. Together they'll fight the toughest opponents they've ever faced. As always... these badass warriors are up for the challenge.
