Beneath the streets of New York lives the tribe of the Avicen, an ancient nation of people with feathers for hair and magic flowing through their veins. Ancient spells keep them hidden from humans, except for one. Echo is a runaway pickpocket who survives by selling stolen treasures on the black market, and the Avicen are the only family she has ever known. Echo is clever and daring, and sometimes she can be defiant, but above all, she is incredibly loyal. When an age-old war reaches the borders of her home, she decides it's time to act. Legend has it that there is a way to end the conflict once and for all: to find the Firebird, a mythical entity believed to possess power the world has never seen. It won't be an easy mission, but if life as a thief has taught Echo anything, it's how to chase what she wants... and how to get it. But some jobs are not as simple as they seem. And this one might set the world on fire.
