It was right before Summertide, when the planet Quake would orbit closest to its sunlight, subjecting itself to vast tidal makes. It was to end up being the most violent Summertide ever, creating something that only happened every 350,000 years.

Access to the unstable Quake was supposed to be prohibited, however, many very insistent travelers were determined to help make the trip. Professor Darya Lang, who examined artifacts left from the long-vanished aliens known as the Builders, experienced a hunch that she will dsicover the Builders themselves. And Councilor Julius Graves was hunting murderers. Planetary Administrators Hans Rebka and Utmost Perry got no choice but to visit Quake, risking their lives to safeguard the others-and to understand, just maybe, the trick of Summertide and the Builders.
