Beneath the streets of New York City live the Avicen, an ancient race of people with feathers for hair and magic running through their veins. Age-old enchantments keep them hidden from humans. All but one. Echo is a runaway pickpocket who survives by selling stolen treasures on the black market, and the Avicen are the only family she's ever known.
Everything in Echo's life changed in a blinding flash when she learned the startling truth: She is the firebird, the creature of light that is said to bring peace. The firebird has come into the world, but it has not come alone. Every action has an equal and opposite reaction, and Echo can feel a great and terrible darkness rising in the distance. Cosmic forces threaten to tear the world apart.
