Erica gave the obligatory chuckle, and gulped the dregs of her latte. “Roswell freaks, Backwash communes—maybe you’ve got the right idea. Lock yourself behind a fence. At least you won’t get nabbed by some damn Colist cult.”

Maddy had to admit she had been, for the most part, shielded at West Point from the aftermath of the Colorado River Backwash. But even so, she knew it was the defining event in people’s lives. Like so many of those who had flocked to the spot where Hoover Dam once stood, she had wanted to witness it as well—to watch the waters of the Colorado River flow upward, in a rising backwash against the pull of gravity, into Lake Mead, if only to prove to her doubting spirit that it ever really happened. Then maybe she, too, might have joined so many others, searching the waters for the body of the martyred Dillon Cole.

Maddy knew it was more than Hoover Dam that had shattered that day. The very nature of creation was shaken to its foundations. If they had suddenly discovered that the world was flat, its consequences could not have been more far reaching than the physical impossibility of a mighty river crashing uphill at a thirty-percent grade. In a matter of days cults began to spontaneously generate on society’s fringes and had quickly germinated into the mainstream. Maddy had found it both frightening and wondrous.

A United 747 came in for a landing and Maddy watched idly as its tires squealed to earth, setting off a tiny puff of smoke on the tarmac. In a moment the jet was a beast of the ground again, ponderous metal that seemed too impossibly heavy to fly. But here was a case of mind over matter—science over perception, mused Maddy. No matter how heavy a plane appeared, Bernouli’s principle assured flight every time a mechanically sound jet sped toward the dead end of the runway. There had always been some comfort in the fact that some natural laws could never be repealed. Slim comfort now.
