Wyrms
Orson Scott Card
 King Oruc, fearing Patience or Peace could be a danger to his reign, keeps them under control by allowing only one of them to leave the castle at a time. However, this delicate hostage situation falls apart when Peace becomes ill. Before he dies, Peace cuts into his shoulder to retrieve a crystal globe hidden under his skin. "The scepter of the Heptarchs," he says. "Never let a gebling know you have it." Only moments after Peace dies, King Oruc sends an assassin after Patience. She easily dispatches him and leaves the castle, stopping to visit her father's preserved head in Slaves' Hall, where the heads of the wisest people are kept alive by headworms. Since the heads are coerced to speak only the truth, Patience forces her father to divulge his darkest secrets. Peace reveals that since Patience's birth, he had been fighting a powerful compulsion to bring her to Cranning, home of the geblings. The "Cranning Call," as it was known, drew the world's greatest thinkers and achievers to make a pilgrimage to Cranning, never to be seen or heard from again. Peace says the source of the Call is the Unwyrm, attempting to summon Patience to his lair. Outside the castle, Patience feels the Cranning Call and decides she will go to Cranning to challenge the Unwyrm. Even as the Cranning Call becomes stronger and more urgent, she chooses her own routes towards the city in defiance of the Unwyrm's power. Patience, joined by Angel and a massive river woman named Sken, eventually meets Ruin and Reck, twin brother and sister geblings who are together the king of the geblings. All their lives, Ruin and Reck had been repelled from Cranning by the Unwyrm, but the Cranning Call surrounding Patience cancels the repulsion and allows them to travel with her. Will, the silent but strong human who had lived as Reck's slave, joins their party. They stop by a house advertising simply ANSWERS. The owner, a dwelf named Heffiji, gives them a crash course in the strange genetics of Imakulata, in which every native plant or animal derives from a single originating species: a black segmented insect, or wyrm. Heffiji also explains that the scepter Patience had retrieved from her father's shoulder was the mindstone of the gebling king, stolen 300 generations ago by the Heptarch. Surgically implanted, it transfers the memories of the previous owners to the current host while absorbing new memories. Ruin - a skilled surgeon - agrees to insert the crystal into Patience's brain. Patience spends the next 40 days half-crazy, processing the memories of previous Heptarchs and the alien minds of gebling kings. She relives the moment when the Starship Captain, lured through lust to the surface, mates with the Wyrm in its lair beneath a glacier that would later become Cranwater. The Wyrm gave birth to the geblings, dwelfs and gaunts - and then finally to a giant wyrm-like child called Unwyrm. Finally, Patience understands the Cranning Call is summoning her to mate with the Unwyrm, so that he can impregnate her with Kristos, a superior human race. This improved species would outcompete humans as well as the dwelf, gebling, and gaunt variants produced by the first-generation mating between the Wyrm and the Starship Captain, eventually becoming the dominant form of life on Imakulata. Even as her lust for Unwyrm grows, Patience knows she must kill him or the world will be doomed. She explains it all to the rest of her companions, and they continue their journey to meet and hopefully kill Unwyrm before he is able to bring his dark plans to fruition. When it is all over Patience hopes to take her place as Heptarch and unite all of the planet's species together in peace.
