(digital ARC) Nerdtastic! Doctorow has a gift for keeping me interested in the technological details of his story, giving just the right level of explanation so that I understand the concepts but don't glaze over and miss something important. This is a fast-paced, ultra-modern thriller with disturbingly real components and great characters. Fans of Little Brother will not be disappointed. Reading this in electronic form added to the creepy realism.
