Booth stormed back into Angela's office to see her and Hodgins talking quietly. He hesitated in the doorway, not sure he should interrupt. It occurred to him that he probably wasn't the only one scared out of his mind at that very moment.

Angela and Hodgins were what he'd always hoped he and Bones could be. Attentive, caring, and passionate, they were perfect for each other. The baby would be lucky to have them as parents.

"You should go home," he said to the two of them. "The baby needs you to sleep."

"I'll sleep on the couch," Angela said, and Booth didn't argue. If she needed to leave, Hodgins would make sure she was taken care of.

"What's the box on the map now?" Booth asked.

"It's the dead zone," Angela explained. At Booth's panicked look, she hurried to explain. "For phones. It's the area of the region that has no cell phone signals. Her phone never registered on another tower, which makes me pretty sure she's somewhere in that box."

The sheer size of it made Booth sick to his stomach. "I just saw stars. Wherever she is, it's clear enough she can see the sky."

"There are lots of open spots out there. If you're right, and she's off trail, it's only going to make our job more difficult."

"Did anyone call Max or Russ? Maybe they'd know what she was doing?"

"I called earlier," Hodgins said. "Max is unreachable, some boat trip with a new girlfriend. Russ said they used to camp in this area all the time. A different place each time. He said he might be able to remember some of the places they'd been, but he didn't think he could narrow it down much."
