Waging a Secret War.
WITHOUT REGRET.
To Prevent . . . a World War.

Against all odds, Colonel Hunter Stark and FBI Special Agent Monica Cruz must cross the lines of morality and justice in order to track down the perpetrators of a heinous crime that threatens to bring modern civilization to the very brink of a nuclear apocalypse.

In a tragic turn of events, Kim Jong-un, President of North Korea, is assassinated during an official visit to the United States.

On the surface, it appears as if the attack was carried out by the Japanese Mafia. And since it occurred on American soil, it makes the surviving and paranoid leadership in Pyongyang believe this could be the precursor to a long-feared invasion.

As the U.S. Seventh Fleet comes under attack in the Sea of Japan, American President Laura Vaccaro orders Stark and Cruz to unearth the proof she needs to exonerate America and Japan before North Korea and its allies -- China and Russia -- escalate the conflict into an all-out shooting war.

It is a haunting journey of unthinkable plots, special ops, thrilling naval battles, and unsavory alliances -- a journey into the heart of darkness, without mercy, without fear . . . WITHOUT REGRET.
