One Shot by Lee Child
"Six shots. Five dead. One heartland city thrown into a state of terror. But within hours the cops have it solved: a slam-dunk case. Except for one thing. The accused man says: You got the wrong guy. Then he says: Get Reacher for me.

And sure enough, ex–military investigator Jack Reacher is coming. He knows this shooter—a trained military sniper who never should have missed a shot. Reacher is certain something is not right—and soon the slam-dunk case explodes.

Now Reacher is teamed with a beautiful young defense lawyer, moving closer to the unseen enemy who is pulling the strings. Reacher knows that no two opponents are created equal. This one has come to the heartland from his own kind of hell. And Reacher knows that the only way to take him down is to match his ruthlessness and cunning—and then beat him shot for shot."

Excellent thriller. Lee Child is reliable as ever.

The Hard Way by Lee Child
"Jack Reacher was alone, the way he liked it, soaking up the hot, electric New York City night, watching a man cross the street to a parked Mercedes and drive it away. The car contained one million dollars in ransom money because Edward Lane, the man who paid it, would do anything to get his family back.

Lane runs a highly illegal soldiers-for-hire operation. He will use any tool to find his beautiful wife and child. And Jack Reacher is the best manhunter in the world.

On the trail of vicious kidnappers, Reacher learns the chilling secrets of his employer’s past . . . and of a horrific drama in the heart of a nasty little war. He knows that Edward Lane is hiding something. Something dirty. Something big. But Reacher also knows this: He’s already in way too deep to stop now. And if he has to do it the hard way, he will."

It's never the villain you thought it was! Lee Child throws in plot twists and turns galore and comes to a satisfying ending.
