From The New York Times best-selling author of Bone comes a stark, gritty sci-fi series about a dimension-jumping art thief -- a man who races through space and time searching for his next big score -- and trying to escape his past. Known only by the four-letter word found spray-painted at the scene of a crime, RASL stumbles across a mystery that spans centuries and not only threatens to expose his illicit activities but also could uncover one of the world's most dangerous secrets.
