Mia watched with wide eyes as Ford tapped on the ground, then listened, then tapped some more.
"Genius," Daniel commented before Anaisa hushed her son.
Mia was inclined to agree, once she finally figured out that Ford was not simply testing the ground for something, but communicating with someone, presumably Martin.
"All right, stand back," Ford told everyone after several minutes of tapping. "He wanted to know who was calling him, but I've finally explained enough to make him come."
The others obediently jumped away from the place he indicated, and waited… and waited.
"How long will this take?" Daniel asked.
"Be patient," Anaisa chided.
The ground began to rumble slightly, and Mia swayed back. Her father caught her arm to steady her, and drew her back a little further.
The stone she'd uncovered suddenly seemed to burst from the ground as it moved its position.
