Unlike the days before the threat of avalanches, the tubeway over the Sierra Nevada range was not heavily traveled. Twice in the past year avalanches had dislodged the tube, once resulting in a number of deaths—something that hadn't happened on American highways for nearly fifty years. But it was the most direct route to the Detroit Glacier Control Center.

"I'm not sure you made a wise choice in Kotenko," Marta said. She sat next to Chandler on the rear observation deck, occupying Professor Kotenko's seat while he chose to mingle with the passengers in the main lounge.

"Why?" asked Chandler.

"Well, I'm not much of a politician." She glanced around before continuing. "It'll be another century before Europe forgets World War III. Maybe you thought Kotenko's selection would appease the Eastern Union or maybe you were simply trying to get him out of the role of principal opponent, but—"

"I picked him because I needed him."

Marta frowned slightly. "Now it's my turn to ask why."

"Kotenko isn't just another glaciologist or meteorologist," Chandler said. "His forte is pure science—creative science."

"But he's impractical." Marta sat back in her chair. "You were the first to point out the weaknesses of his greenhouse plan. In fact, you were rather vehement about it before the conference. What happened to change your mind?"

Chandler didn't answer. Instead, he stared disinterestedly at the snowy moonlit peaks distorted by the curvature of the transparent tubeway walls. Marta touched his arm.
