The treatment was more or less successful. Her damaged body and brain were reconstructed according to templates written in her DNA. For obvious reasons, she remembered nothing of her life before the accident. Her salvation was a second birth, and Sulean had relearned the world the way an infant learns it, acquiring language a second time and crawling before she took her first (or second) tentative steps.

But there was a drawback to the treatment, which was why it was so rarely used as a medical intervention. It conferred its customary longevity, but it also interrupted the natural cycle of her life. At puberty, every Martian child developed the deep wrinkles that made Martians appear so distinctive to Terrestrials. But that didn't happen to Sulean. She remained, by Martian standards, sexless and grotesquely smooth-skinned, an overgrown infant. When she looked in a mirror, even today, Sulean was inevitably reminded of something pink and unformed: a grub writhing in a rotten stump. To protect her from humiliation she had been sheltered and nurtured by the Fourths who saved her life, the Fourths of Bar Kea Desert Station. At the Station she had a hundred indulgent, caring parents, and she had the dry hills of Bar Kea for a playground.

The only other child at the Station was the boy named Esh.

They had not given him any other name, only Esh.

Esh had been built to communicate with the Hypotheticals, though it seemed to Sulean he could barely communicate even with the people around him. Even with Sulean, whose company he obviously enjoyed, he seldom spoke more than a few words. Esh was kept apart, and Sulean was allowed to see him only at appointed times.

Nevertheless she was his friend. It didn't matter to Sulean that the boy's nervous system was supposedly receptive to the obscure signals of alien beings, any more than it mattered to Esh that she was as pink as a stillborn fetus. Their uniquenesses made them alike and had thus become irrelevant.

The Fourths at Bar Kea Desert Station encouraged the friendship. They had been disappointed by Esh's refractory silences and his outward display of dull-normal intelligence. He was studious but incurious. He sat wide-eyed in the classrooms the adults had designed for him, and he absorbed a reasonable amount of information, but he was indifferent to it all. The sky was full of stars and the desert was full of sand, but stars and sand might have traded places for all it mattered to Esh. Whether he spoke to the Hypotheticals, or they to him, no one could say. He was stubbornly silent on the subject.
