Far to their right was the Brazos River, snaking south toward the Gulf, embroidered in gold thread on the light blue-gray of the distant haze. Ahead, he could already see the rainbow towers of Houston, standing at attention on the skyline in a tight defensive platoon. Houses were becoming noticeably more numerous in the foreground below. At intervals between them, unidentifiable sprawling constructions began to make their appearance—random collections of buildings, domes, girder lattices, and storage tanks, tied loosely together by tangles of roadways and pipelines. Farther away to the left, a line of perhaps half a dozen slim spires of silver reared up from a shantytown of steel and concrete. He identified them as gigantic Vega satellite ferries standing on their launchpads. They seemed fitting sentinels to guard the approaches to what had become the Mecca of the Space Age.

As Victor Hunt gazed down upon this ultimate expression of man's eternal outward urge, spreading away in every direction below, a vague restlessness stirred somewhere deep inside him.

Hunt had been born in New Cross, the shabby end of East London, south of the river. His father had spent most of his life on strike or in the pub on the corner of the street debating grievances worth going on strike for. When he ran out of money and grievances, he worked on the docks at Deptford. Victor's mother worked in a bottle factory all day to make the money she lost playing bingo all evening. He spent his time playing football and falling in the Surrey Canal. There was a week when he stayed with an uncle in Worcester, a man who went to work dressed in a suit every day at a place that manufactured computers. And his uncle showed Victor how to wire up a binary adder.

Not long afterward, everyone was yelling at everyone more often than usual, so Victor went to live with his aunt and uncle in Worcester. There he discovered a whole new, undreamed-of world where anything one wanted could be made to happen and magic things really came true—written in strange symbols and mysterious diagrams through the pages of the books on his uncle's shelves.

At sixteen, Victor won a scholarship to Cambridge to study mathematics, physics, and physical electronics. He moved into lodgings there with a fellow student named Mike who sailed boats, climbed mountains, and whose father was a marketing director. When his uncle moved to Africa, Victor was adopted as a second son by Mike's family and spent his holidays at their home in Surrey or climbing with Mike and his friends, first in the hills of the Lake District, North Wales, and Scotland, and later in the Alps. They even tried the Eiger once, but were forced back by bad weather.
