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 all but one human: Echo, a runaway pickpocket who survives by selling stolen treasures on the black market.

The Avicen are the only family Echo has ever known, so when a centuries-old war crests on the borders of her home, she decides it’s time to act. Legend has it that to end the conflict once and for all, Echo must find the firebird, a mythical entity believed to possess power the likes of which the world has never seen.

It will be no easy task, though if life as a thief has taught Echo anything, it’s how to hunt down what she wants . . . and how to take it. But some jobs aren't as straightforward as they seem. And this one might just set the world on fire.
