Flooded England, 2216 ...Lilly Melkun has outwitted the bloodthirsty reavers, who prowl the waters that cover most of England, and has escaped to Cambridge. But Lilly is far from safe, because still in her keeping is PSAI, the last hand-held computer in existence-a now malfunctioning treasure from the past. Inside the jewel-like computer is a sinister-looking chip with an unknown purpose. Worse follows, when the professors of Cambridge plug it into an ancient mainframe computer, setting in motion a fiery chain of events leading back to London. A false anti-terrorist alert has been activated. Strange, out-of-control robots from a long-ago technological time threaten to use 'maximum force' to control everything in their way. Once again, it's up to Lilly, Zeph and friends to save the world from burning.
