Nearly a thousand years in the future, a sheltered and spoiled girl named Lah Lia was raised for a single purpose--to be sacrificed into the mysterious spacetime diskos that hovers over the Cydonian Pyramid. Just before she is killed, however, a strange boy appears from the diskos, and helps her escape. Now her fate and the boy's--Tucker Feye--are inextricably linked.
In a far distant future, in present-day Hopewell, and on a train platform in 1997, Tucker, Lia, and Kosh must puzzle out the enigmatic Boggsians as they search for one another and the secrets of the diskos.
