The Devil Colony by James Rollins

caught by surprise by the sudden turn.
    “Hold tight!” he hollered.
    But she was not the only one who was surprised by the maneuver.
    Rounds sparked off the stone that shielded them—then the chopper shot past overhead, missing its target. It spun, banking around, pivoting to come at them again.
    Hank had not slowed Mariah. He aimed straight for the diving helicopter. As it swung to face them, he tugged his pistol from his holster. It was a Ruger Blackhawk, powerful enough to deal with the occasional wild bear. He didn’t know if it was an act of war for a Native American to fire upon a National Guard chopper, but he had not started this fight. Plus his goal was not to kill, only to distract.
    He pulled the trigger over and over again as he raced head-on toward the helicopter, emptying the clip. He saw no reason to be reserved. A few rounds even found their target, cracking off the windshield.
    The attack caught the hunters off guard.
    The chopper bobbled, a spate of return fire cut off abruptly, aborted as the vehicle jostled the gunmen. Hank used his heels to urge Mariah onward, ducking straight under the belly of the helicopter. It was so low now that Hank could have reached up and brushed his hand along the landing skids.
    He spotted one of the gunmen hanging out an open hatch overhead, dressed all in commando black. They locked eyes, then Mariah cleared the helicopter. With the thunder of the engines and pound of the rotor wash, the mare needed no further urging.
    Mariah shot for the woods again, diving back into the shadows.
    Kawtch hit the forest’s edge a few yards to the left.
    The chopper’s engines whined into a banshee’s cry as it climbed again and spun after them.
    This cat-and-mouse game could not last forever. They’d been lucky so far, but farther down the mountainside, the alpine forests would dwindle to a smattering of oaks and open fields. The hunters must have known the same. The helicopter sped after them. Their pursuers would not be surprised again.
    Plus Hank was out of bullets.
    A sparkle of silver drew his eyes to the right. A small stream, glacier-cut and flooded with snowmelt and rain from the passing storm, raced down a series of cataracts. He used his knees to guide Mariah toward it.
    Once they’d reached the bank, he goosed Mariah with his heels. She leaped into the middle of the stream with a heavy splash—but from here, they would need to part ways.
    Hank let loose the reins, grabbed Kai’s wrist, and rolled out of the saddle downstream of the horse. With his other hand, he managed a fast slap to Mariah’s rump, both as a good-bye and to get her moving.
    She jumped out of the river as Hank and Kai hit the freezing-cold water. Kawtch splashed next to them. The current grabbed them all and spun them downstream. The last thing he heard before being dragged underwater was a sharp cry from the girl.
    Kai scrambled for the surface, kicking wildly, striking a soft body with her heel. She had been too stunned to react when she was first pulled out of the saddle, but once the cold struck her, it loosed a scream, one trapped inside her since the explosion hours ago.
    Then her mouth was full of water.
    Out of breath from her yell, she choked as her body was flung around. Slick rocks battered her. Ice-cold water swamped her nose. Then her head was above water again. She coughed and cried. Arms scooped her and pulled her toward shore. She tried to scramble out of the river, but strong hands yanked her back into the water.
    “Stay here,” Professor Kanosh hissed. He looked half drowned, his gray hair plastered to his skull. His dog climbed onto a boulder, still standing belly-deep in the stream.
    “Why?” she asked, her teeth already beginning to chatter, both from the cold and the terror.
    He pointed up.
    She searched and spotted the helicopter vanishing over a ridgeline to the west.
    “Body heat,” the professor explained. “It was how they were tracking us so well through the woods,
