Shadow's End by Sheri S. Tepper

I took an oath to rule the world of Kamir. That world, though much diminished, still had seas and forests and animals. You are destroying that world. Greater comprehension would only increase my sense of futility.” The Lost King rose from his throne, turned his back upon his minister, and stalked to a nearby window that stood open to let in the fresh breezes of early spring.
    He had escaped on a day much like this—it had been late fall, not spring, but on a similar day—slipping out this very window in the darkness before dawn, across the velvet lawns, into the trees. Once Tarnen was gone, this royal park would contain all the trees left on Kamir. He had thought of that as he had walked through them that day toward his cache of clothing and money and documents, hidden away bit by inconspicuous bit over a long, long time of preparation. He had emerged on the far side of the trees dressed as an Elithan, and he had slipped into the crowd that always stood there, staring at the palace, to stand for a time himself, staring at the palace, before he went away.
    He had taken ship for Elitha, unremarked, unnoticed, calling himself Osterbog Smyne, a common Elithan name. He had reached Elitha. Oh, with what eagerness had he taken up a new life as a nobody on Elitha. If not for that damnable Leelson Famber, Osterbog Smyne would be on Elitha still, keeping a fruit stall, taking his holidays in the forests, watching birds, maybe even going fishing, far from ministers and reports and briefings and the whole irrelevant, endless fal-de-rol of kingship.
    â€œYour Majesty is so deep in thought, one assumes he is considering marriage and the production of an heir,” said a pontifical voice from behind him. So. The Minister of Agriculture had called for assistance, and here was Lord Zhoun, the Prime Minister, the quintessence of boredom, the paradigm of duty undesired.
    Jiacare Lostre murmured, “I’ve told you, I’ve no intention of begetting a child to carry on this charade. The planet is within a year or so of being Class G. Soon you’ll be directing the aristocracy to turn in their pets for euthanizing. Soon will come Class-J domed cities, which will grow, and grow, until they make a glittering ceiling over the final convulsions! You know how it will end, how it always ends. The Scroll of Establishment contains no requirement that I be part of the process.”
    â€œCommon sense would indicate—”
    â€œCommon sense, hah! Focus on one of my no-doubt-eager brothers or nephews. Groom half a dozen of them for this thankless ascendancy.”
    â€œYour Majesty, please …”
    â€œPrime Minister, please!”
    â€œYou used to call me Uncle.”
    â€œYou used to call me Jickie, Lord Zhoun, and you used to tell stories of adventure and mystery. You used to like to go riding. Remember horses? You even took me fishing once. When father was alive, you were quite a nice fellow.”
    â€œWhen your father was alive, he attended to his duty.”
    â€œIn a manner of speaking, Uncle. My father, though beset by uncontrollable and inappropriate affection for small girls, was in most respects a very good king. He had no convictions to confuse him. He was impressed by ritual and dedicated to traditions. He complied with them well, but then he had certain talents I do not.”
    â€œJickie!”
    â€œIt’s true, Uncle. Father was quite open with me. As I had four older brothers, he felt free to tell me things hewould never have told the heirs. First, he had taught himself not to care about anything but sensation. Then he taught himself to sleep while sitting bolt upright, eyes wide open. He could do this either while upon the throne or upon horseback, and he was invariably asleep while you and the others read your interminable accounts of continuing destruction. He told me this, enjoying his cleverness, without realizing the effect it had on me. Of course, he never thought I’d
