By noon the next day, Sam and Remi were among a dozen volunteers sitting under the hot sun in the back of a flatbed truck, bouncing along the bad road toward Volcán Tacaná. Beside them were their former shipmates Dr. Christina Talamantes and Dr. Maria Garza, and, on the other side, were others they had come to know during the past week. There were two brothers in their twenties named Raul and Paul Mendoza, who had been brought up out in the countryside near the volcano, and a tall, quiet man named José, who’d had a law office in Tapachula that had been damaged by the earthquake. José Sánchez had a thick mustache that veiled his mouth, so one seldom knew whether he was smiling or frowning.

As they rode away from the city past miles of cultivated fields on their way into the interior, Remi stared into the distance at the blue triangle of Tacaná. Christina Talamantes noticed. “There doesn’t seem to be any more smoke. Maybe it’ll settle down again for another hundred years or so.”

“And maybe it’s saving its strength to spit fire and ash on our heads and bury us in lava,” José said. “The word ‘Tacaná’ is Mayan for ‘House of Fire.’”

“Let’s hope it doesn’t live up to its name, for now,” Sam said.

They rode for another hour before they reached the small town of Unión Juárez. There were two small brick buildings along the main street that had partially collapsed and two others that had lost some roof tiles. In the central square, the driver and the Spanish-speaking volunteers got out to talk with the people loitering there. Sam and Remi stuck close to Christina, who obliged them by translating. After talking briefly with an Indian-looking couple, Christina told the Fargos, “The road ends in about seven kilometers.”

“Then what?” asked Sam.

“Then we walk,” she said. “The lady says it’s a foot trail, and there are lots of smaller trails branching off of it that lead to the mountain villages.”

Remi said, “Did she say anything about conditions up there?”

“She warned me that it will be cold. It’s over thirteen thousand feet at the top.”

“We’re ready for that,” Remi said. “In fact, I have some things I can share with you. I brought some shells and fleece linings on the yacht because sometimes the Pacific can be cold at night, especially when the wind blows.”

“Thank you,” said Christina. “I brought some warm clothes too, and so did Maria, because we thought we’d be sleeping outdoors. But we may take you up on your offer in a day or two.”

“Did the lady say anything else?”
