Marcus is a wonderfully developed character: hyperaware of his surroundings, trying to redress past wrongs, and rebelling against authority. Teen espionage fans will appreciate the numerous gadgets made from everyday materials. One afterword by a noted cryptologist and another from an infamous hacker further reflect Doctorow’s principles, and a bibliography has resources for teens interested in intellectual freedom, information access, and technology enhancements.
