From the publishers blurb:
he Amaranthine Sorcerers, rulers of their self-named city, are servants of an entity that demands dreams as payment for their gifts of sorcerous powers. But the sorcerers themselves grew fond of these dreams, or perhaps the magic they received from this entity imparted them with this obsession with the oneiric.
Now they hoard dreams. They collect them as kings collect treasures from the realms they conquer. They covet the dearest dreams of others. They steal dreams from one another, in a strange rivalry, as great as any mortal foe. But they are never satisfied.
Others also covet those dreams, especially those that lost them to this greedy cabal. They seek brave adventurers to venture into the sorcerers’ inner citadel and recover them. For a great reward, of course. But are these rewards worth the great risk of challenging sorcerers that can manipulate both your dreams and your worst nightmares?
