The Angel and the Brown-Eyed Boy: Promo

From Goodreads:
Eliana made her way along the sidewalk, knowing that she was dirty, feeling the grit in her hair and on her skin. When she had reached the planet's atmosphere, clothes and all sorts of things had rushed at her with great force, tossing her over and over. Dirt had come, too. She'd found the clothes she needed and put them on the way her teachers had shown her. Then her people had put her where she was....

NEW YORK CITY ON THE EVE OF ARMAGEDDON, IN THE LATE 22nd CENTURY--PERHAPS 

Mistaken for a Russian ballet dancer, Eliana finds her destination-the Hermitage Academy, a famous high school for the arts. Soon she discovers that this Earth is a strange and violent place, where people live in fear, and where her very presence makes some want to protect her and others want to hurt her. It is a century after the second Russian revolution, when technology was outlawed and Tsar Yuri took over most of world, ushering in the "Great Peace." For the U.S. president, Lincoln Charles, peace is doable-just focus on the positive, project a trustworthy image, and make sure that dissenters are taken care of quietly, permanently. Something terrible, though, is about to happen; and for Eliana, not much time remains to find the "Golden Boy..""
