Mile 81 (Kindle Single)

With the heart of Stand By Me and the genius horror of Christine, Mile 81 is Stephen King unleashing his imagination as he drives past one of those road signs…
At Mile 81 on the Maine Turnpike is a boarded up rest stop on a highway in Maine. It’s a place where high school kids drink and get into the kind of trouble high school kids have always gotten into. It’s the place where Pete Simmons goes when his older brother, who’s supposed to be looking out for him, heads off to the gravel pit to play “paratroopers over the side.” Pete, armed only with the magnifying glass he got for his tenth birthday, finds a discarded bottle of vodka in the boarded up burger shack and drinks enough to pass out.
Not much later, a mud-covered station wagon (which is strange because there hadn’t been any rain in New England for over a week) veers into the Mile 81 rest area, ignoring the sign that says “closed, no services.” The driver’s door opens but nobody gets out.
Doug Clayton, an insurance man from Bangor, is driving his Prius to a conference in Portland. On the backseat are his briefcase and suitcase and in the passenger bucket is a King James Bible, what Doug calls “the ultimate insurance manual,” but it isn’t going to save Doug when he decides to be the Good Samaritan and help the guy in the broken down wagon. He pulls up behind it, puts on his four-ways, and then notices that the wagon has no plates.
Ten minutes later, Julianne Vernon, pulling a horse trailer, spots the Prius and the wagon, and pulls over. Julianne finds Doug Clayton’s cracked cell phone near the wagon door — and gets too close herself. By the time Pete Simmons wakes up from his vodka nap, there are a half a dozen cars at the Mile 81 rest stop. Two kids — Rachel and Blake Lussier — and one horse named Deedee are the only living left. Unless you maybe count the wagon. List Price: $ 3.99

The Moonlit Mind: A Tale of Suspense (Kindle Single)

In this chilling original stand-alone novella, available exclusively as an eBook, #1 New York Times bestselling author Dean Koontz offers a taste of what’s to come in his new novel, 77 Shadow Street, with a mesmerizing tale of a homeless boy at large in a city fraught with threats . . . both human and otherwise.
Twelve-year-old Crispin has lived on the streets since he was nine—with only his wits and his daring to sustain him, and only his silent dog, Harley, to call his friend. He is always on the move, never lingering in any one place long enough to risk being discovered. Still, there are certain places he returns to. In the midst of the tumultuous city, they are havens of solitude: like the hushed environs of St. Mary Salome Cemetery, a place where Crispin can feel at peace—safe, at least for a while, from the fearsome memories that plague him . . . and seep into his darkest nightmares. But not only his dreams are haunted. The city he roams with Harley has secrets and mysteries, things unexplainable and maybe unimaginable. Crispin has seen ghosts in the dead of night, and sensed dimensions beyond reason in broad daylight. Hints of things disturbing and strange nibble at the edges of his existence, even as dangers wholly natural and earthbound cast their shadows across his path. Alone, drifting, and scavenging to survive is no life for a boy. But the life Crispin has left behind, and is still running scared from, is an unspeakable alternative . . . that may yet catch up with him. List Price: $ 2.9

Three Cups of Deceit: How Greg Mortenson, Humanitarian Hero, Lost His Way (Kindle Single)

Greg Mortenson has built a global reputation as a selfless humanitarian and children’s crusader, and he’s been nominated for the Nobel Peace Prize. He is also not what he appears to be. As acclaimed author Jon Krakauer discovered, Mortenson has not only fabricated substantial parts of his bestselling books Three Cups of Tea and Stones into Schools, but has also misused millions of dollars donated by unsuspecting admirers like Krakauer himself.
This is the tragic tale of good intentions gone very wrong.
