The Fold by Peter Clines.
Here is the Description from Amazon:
The folks in Mike Erikson's small New England town would say he's
just your average, everyday guy. And that's exactly how Mike likes it.
Sure, the life he's chosen isn’t much of a challenge to someone with his
unique gifts, but he’s content with his quiet and peaceful existence.
is, until an old friend presents him with an irresistible mystery, one
that Mike is uniquely qualified to solve: far out in the California
desert, a team of DARPA scientists has invented a device they
affectionately call the Albuquerque Door. Using a cryptic computer
equation and magnetic fields to “fold” dimensions, it shrinks distances
so that a traveler can travel hundreds of feet with a single step.
invention promises to make mankind’s dreams of teleportation a reality.
And, the scientists insist, traveling through the Door
is completely safe.
Yet evidence is mounting that this
miraculous machine isn’t quite what it seems—and that its creators are
harboring a dangerous secret.
As his investigations draw him
deeper into the puzzle, Mike begins to fear there’s only one answer that
makes sense. And if he’s right, it may only be a matter of time before
the project destroys…everything.
