Penguin Roc is on quite a roll these days, introducing one fine new talent after another. September spotlights Carol Berg, a spectacular new voice in fantasy fiction. TRANSFORMATION (4.5) centers around the changing relationship of two men, one a lowly slave, the other a mighty prince, heir to the Derzhi Empire. At first, the slave Seyonne seeks only to survive. Numb to almost any punishment after being stripped of his magical powers upon capture, he nevertheless finds his interest caught by the amazing potential he discovers in the prince. And when an evil conspiracy leaves the prince a fugitive, only Seyonne can save his master and the rest of the world from a dark fate. Superbly textured, splendidly characterized, this spellbinding tale provides myriad delights for the fantasy connoisseur.
