Zak Killian hears a voice. Could it be a guardian angel? A ghost? No, that’s crazy. But sometimes the voice is so real…It warns him of danger—directs him to safety. Then one day Zak is standing on the subway platform when the voice warns him to run. The tunnel starts to fill with water. His friends Moira and Khalid believe this is more than a premonition, and soon all three find themselves in an alternate universe that is both familiar and seriously strange. As Zak unravels the mystery behind the voice, he faces decisions that may mean the end of their world at home—if they can even get home!

Barry Lyga is a recovering comic book geek. According to Kirkus, he's also a "YA rebel-author." Somehow, the two just don't seem to go together to him. When he was a kid, everyone told him that comic books were garbage and would rot his brain, but he had the last laugh. Raised on a steady diet of comics, he worked in the comic book industry for ten years, but now writes full-time because, well, wouldn't you? The Astonishing Adventures of Fanboy & Goth Girl is his first novel. Unsoul'd is his latest. There are a whole bunch in between, featuring everything from the aftermath of child abuse to pre-teens with superpowers to serial killers. He clearly does not know how to stick to one subject.
