They reached the causeway a few minutes later, and Kira practically shook with relief to see it still intact. They kept to the center as they crossed, staying as far from the water as they could. As a gesture of goodwill, Kira deferred the next decision to Green.

“Where to now?”

Green grunted softly as they jogged past a boathouse with an open parking lot. “If we cut south, we’ll have miles to run before we’re clear of the lake,” he said. “Obviously they can come up on land just fine, but I figure the more we can avoid water, the better.” Sure enough, the road curved more and more to the left, before finally just turning sharply and leading them straight south. The road appeared to be the edge of the little lake community, with nothing but forest on the far side, and the two of them plunged into the trees to cut across and leave the lake behind.

“Watch out for border markers,” said Kira. “I found them on my way in—they used link data, concentrated like in the house, to set up a perimeter and warn people away. If you start to get freaked out for no reason, that’s the reason.”

Green said nothing but nodded in acknowledgment.

They picked their way silently through the thick forest, and it wasn’t long before they reached another road, but soon this, too, turned south, and they set back off into the woods. They crossed two more hills and a narrow stream before the sun began to come up, and when the next road turned out to be a wider, two-lane highway, they decided to risk a little southward travel. Almost immediately, though, the road cut back east toward the lake, as if the land itself was determined to twist them around and lead them back to danger. They struck out into the trees once more, but Kira was exhausted and starving and cold. Finally she stopped them in the backyard of an abandoned house.

“We need to figure out where we are.”

Green nodded toward the house. “Think they have a map?”

“You check the bookshelves, I’ll check for a den or an office.”

Green shook his head. “You never look in a house for a map, you look in the cars.” He led her around to the front, where two cars sat in the driveway. Kira started toward them, but he shook his head. “Too nice—all the rich humans had maps on computers, especially in their cars, and a lot of the middle-class ones, too. You want to find a paper map, find the oldest, nastiest car you can see.”
