Andy Vanavarre has it rough. In class, he’s the target of constant ridicule, commanded by Letty, bully extraordinaire. But today something’s different: he stood up for the new kid, challenged his classroom tormentor, and-if that’s not enough-his eyes are changing color.Andy soon discovers that he is destined for a role in a timeless conflict; disguised and undetected, humanity’s greatest threat culls the Seers. These potential champions are humankind’s only defense-distinguished by their violet eyes, and the penetrating sight which they provide. After an ill-fated trip to the optometrist, Andy learns that Letty, another unwitting hero, has been captured by the enemy, and taken to the Netherscape.From floating cities to butler crabs, Andy encounters wonders and horrors that he could never have imagined. The trail of his one-time bully leads him to the city of Caspia, and to its mistress, the immortal Pythia: an oracle who exchanges prophecies for Seer children, and to whom Letty is now belongs. But Pythia has her own agenda, and soon Andy finds that his body-and his will-may not be his alone.Surrounded by enemies who hunt them by instinct, and allies morally shattered by endless conflict, Andy and Letty must retain their freedom-and their lives-as they race to flee the Netherscape.
