Avatars, Book One
Something was different. She stepped hesitantly out of the subway car, her boots sounding even louder now. What was it? 

The graffiti. Had that been there before? 

Emblazoned across the far wall in huge silver letters: 

The end has come. 

In New York, Kali wakes to an empty subway car, and an even emptier city. Venus and Gus survive an earthquake in Los Angeles and realize they have to deal with more than just the aftershocks. In Chile, Tigre finds himself in an unfamiliar jungle, and strangely not alone. And Amon, in Egypt, can see his path but is blind to the full picture. 

They are suddenly trapped in a deserted world, five teenagers with no hope of escape. Why have they survived? What force—or intelligence—connects them? Drawn inexorably toward one another, they only know their future involves an experience outside anything they could have imagined. Fantasy newcomer Tui T. Sutherland creates a future in which teens have the power to complete the destruction of Earth—or to save it.

Tui T. Sutherland
Tui T. Sutherland was born on July 31, 1978 in Caracas, Venezuela. Her mother, who is from New Zealand named her after the tui, a bird native to that country. Sutherland lived in Asuncion, Paraguay; Miami, Florida; and Santo Domingo, Dominican Republic; before moving to New Jersey in high school. While in high school she began doing theater, which consisted mostly of backstage work.

Sutherland graduated from Williams College in 1998, after which she abandoned her ideas of a career in theater in favor of a career in fiction writing, which she found to be more stable. At the time of this writing, she was living in Boston, Massachusetts, with her husband and their two children. -- bio adapted from Wikipedia
