Never Go Back by Lee Child.
"Since talking to Maj. Susan Turner on the telephone from South Dakota in 2010's 61 Hours (bestseller Childs's 14th Jack Reacher novel), the former military cop has been heading to the Virginia headquarters of his old unit, the 110th MP, in hopes of meeting her. In this 18th outing, Reacher finally arrives in Virginia, where his plan to meet Turner is initially thwarted by thugs who want to keep them apart. An arrest for a crime Reacher doesn't remember committing 16 years earlier provokes him to run, kicking off a cross-country odyssey. As usual, head-busting physicality and analytical problem solving play key roles in Reacher's fight to prove his innocence and expose his enemies. Manhunts on both coasts, a link to corruption in Afghanistan in the wake of the U.S. military drawdown, and the possibility for romance between Reacher and Turner make this entry one of the best in the series."

Thankless in Death by J.D Robb (Nora Roberts)
"Lieutenant Eve Dallas has plenty to be grateful for, especially Roarke’s big Irish family, which is a joyful improvement on her own dark childhood.

Other couples aren’t as lucky. The Reinholds, for example, are lying in their home stabbed and bludgeoned almost beyond recognition. Those who knew them are stunned—and heartbroken by the evidence that they were murdered by their own son.

Turns out that twenty-six-year-old Jerry is not only capable of brutality but has taking a liking to it. With the money he’s stolen from his parents and a long list of grievances, he intends to finally make his mark on the world. Eve and her team already know the who, how, and why of this murder. What they need to pinpoint is where Jerry’s going to strike next."

Concealed In Death by J.D. Robb
"In a decrepit, long-empty New York building, Lieutenant Eve Dallas’s husband begins the demolition process by swinging a sledgehammer into a wall. When the dust clears, there are two skeletons wrapped in plastic behind it. He summons his wife immediately—and by the time she’s done with the crime scene, there are twelve murders to be solved.

The place once housed a makeshift shelter for troubled teenagers, back in the mid-2040s, and Eve tracks down the people who ran it. Between their recollections and the work of the force’s new forensic anthropologist, Eve begins to put names and faces to the remains. They are all young girls. A tattooed tough girl who dealt in illegal drugs. The runaway daughter of a pair of well-to-do doctors. They all had their stories. And they all lost their chance for a better life.

Then Eve discovers a connection between the victims and someone she knows. And she grows even more determined to reveal the secrets of the place that was called The Sanctuary—and the evil concealed in one human heart."

Like A Mighty Army by David Weber
"For centuries, the world of Safehold, last redoubt of the human race, lay under the unchallenged rule of the Church of God Awaiting. The Church permitted nothing new—no new inventions, no new understandings of the world.

What no one knew was that the Church was an elaborate fraud—a high-tech system established by a rebel faction of Safehold’s founders, meant to keep humanity hidden from the powerful alien race that had destroyed old Earth.

Then awoke Merlyn Athrawes, cybernetic avatar of a warrior a thousand years dead, felled in the war in which Earth was lost. Monk, warrior, counselor to princes and kings, Merlyn has one purpose: to restart the history of the too-long-hidden human race.

And now the fight is thoroughly underway. The island empire of Charis has declared its independence from the Church, and with Merlyn’s help has vaulted forward into a new age of steam-powered efficiency. Fending off the wounded Church, Charis has drawn more and more of the countries of Safehold to the cause of independence and self-determination. But at a heavy cost in bloodshed and loss—a cost felt by nobody more keenly that Merlyn Athrawes.

The wounded Church is regrouping. Its armies and resources are vast. The fight for humanity’s future isn’t over, and won’t be over soon."
