According to the sensor, they were to head north. Tiernan clenched his jaw in frustration. He hated depending on Andreas and his super-sensor, but Caleb’s trail had disappeared before they’d reached the Jeep and he really had no alternative. Someone was helping Caleb evade them. Someone was covering his trail, and apparently, even masking his shifts, making it more difficult for the sensor to track him. So . . . north. That was the extent of their instructions. “So what’s north?” Ava mused, half to herself. “Idaho, Wyoming, Montana . . .” “Canada,” Tiernan said when she paused. He might have imagined it, but he could have sworn Ava stiffened a bit at that. “What?” he asked. Emma leaned forward over the seat. “I think Canada,” she said. “Why do you say that?” Tiernan made a turn onto the highway and floored it. The Jeep shuddered in protest but slowly sped up. “I overheard some of them talking,” she said. “They said something about Ontario.”
