They know the law can’t touch them. But there’s another kind of justice.

Army veteran Mason Sharpe is working as a junior deckhand on a Great Lakes freighter. The work is hard, but the pay is fair, and Mason is enjoying this simple life.

Then the boat breaks apart in a savage storm on Lake Superior. Mason survives the freezing swells, but his close friend and fellow crewman, Evan, is lost to the deep

Returning Evan’s classic Mustang to his young widow, Grace, Mason discovers that a shadowy shipping conglomerate is squeezing traumatized families to sign quick hush-money contracts, subtly shifting the blame for the disaster onto the dead crew.

When a whistleblower is silenced right before Mason's eyes, he realizes the ship’s owners will do whatever it takes to bury the truth. This sinking wasn’t a simple accident, it was negligent homicide.

And Mason isn’t going to stand idly by while ruthless corporations protect their own bottom line by threatening the families of his fallen friends. It’s time to take the gloves off.

The bad guys are about to discover they’ve created their own worst nightmare—a full-on Mason Sharpe Shock Wave.

Shock Wave – book 15 of the stunning Mason Sharpe action thriller series. Perfect for fans of Lee Child, Jason Kasper and David Archer.
