Ercy Farris, heir apparent to the House of Zeor, lives in a time when humanity has mutated into predatory Simes, and their prey, Gens, who produce the selyn which the Simes need to survive…and will kill to get. Centuries ago, a Sime-submutation appeared, the channels, with the ability to take selyn from Gens without killing and to transfer it to Simes. Now, a complex social structure rules the world, with the channels at the top, preventing Simes from killing Gens.
Ercy, a not-yet-matured channel, has dedicated her life to cultivating the mahogany trinrose, source of the drug kerduvon, which legend says can free humanity of the threat of the kill.
Pursuing the secret of the mahogany trinrose during her changeover into an adult Sime, she wakens in herself powers outlawed by her society as witchcraft: telekinesis, clairvoyance, teleportation…and the strange power to make her wishes come true. Yet as they come true, they make her into a danger to her Householding and her world.
One man, the mysterious Halimer Grant, can help her in the desperate struggle to preserve those she loves and their ideals. What price does he foresee that makes him hesitate?
