be virtually present as a hologram anywhere in the world where the nodes are available. Most students learn via distance education but are able to attend physically when asked. One exception is Bertie Todd who lives halfway across the US. Bertie has contacts in Siberia and admits to being on a committee that controls a distance learning graduate "student" at MIT. It is hinted that Bertie is a virtual entity himself, though Juan Orozco has visited his home virtually and cannot see why anyone would fake that. Fairmont High believes that it is important that their students be able to operate both on-line and off-line; thus, one of their exams must be completed while isolated from the network. This exam is a project of the students' choosing, and one grading criterion is to generate income for the school. It turns out that Bertie has been subtly manipulating some students, and entices Miriam Gu to team up with Juan despite them never having spoken before and their different personalities (another positive grading criterion). Bertie has also been supplying Juan with memory-enhancing drugs which enable him to structure large queries to the network in ways that ordinary people cannot, and Juan has been helping him with some of his outside research. Miriam has decided to investigate strange goings-on in Torrey Pines State Natural Reserve for their project. Nodes are not permitted because of the toxic components that would remain when they failed. Just before they go offline, Bertie mail-drops (via Fedex personal rocket) some new biodegradable network nodes that his MIT persona has been developing. He asks Juan to test them in the forest as part of his unlimited exam, where projects can make use of any resources available (doing two projects concurrently is a third positive grading criterion). Bertie does not tell Juan how to interact with the nodes' software, in the hope that Juan will be forced to send a high-powered signal from inside the forest to ask for outside help – not only failing the offline restriction of the exam, but also allowing Bertie to receive data from the nodes and steal Miriam and Juan's project. Miriam and Juan are accompanied into the forest by William, her grandfather who is growing a new nervous system and personality as part of an Alzheimer's treatment. Using video from the nodes, which are mistaken for food, they discover a group of intelligent
