WWW trilogy

A sentient World Wide Web entity known as Webmind has befriended Caitlin Decter and grown eager to learn about her world. But Webmind has also come to the attention of WATCH--the secret government agency that monitors the Internet for any threat to the United States-and they're fully aware of Caitlin's involvement in its awakening. WATCH is convinced that Webmind represents a risk to national security and wants it purged from cyberspace.
