In the aftermath of the “summertide” that nearly destroyed twin planets of Opal and Quake, a few humans and aliens representing various civilized worlds confront the remnants of an ancient technology and discover a threat to life as they know it. Excitement builds rapidly in this fast-paced sequel to Summertide. Recommended for large libraries

It was just before Summertide, the time when the twin planets, Opal and Quake, would orbit closest to their sun, subjecting both — but Quake in particular — to vast tidal forces. And it was to be the most violent Summertide ever, due to the Grand Conjunction of the system’s stars and planets, something that happened only every 350,000 years. Access to the unstable Quake was supposed to be prohibited, but some very insistent travelers were determined to make the trip. Professor Darya Lang, who had made a career studying artifacts left by the long-vanished aliens called the Builders, had a hunch that during this unusal Summertide she might find the Builders themselves. Louis Nenda and the Cecropian Atvar H’sial had their own interests in Quake, and would do anything to get there. And Councilor Julius Graves was hunting murderers — if they were hiding on Quake, he needed no one’s permission to search for them. Planetary Administrators Hans Rebka and Max Perry had no choice but to go to Quake themselves — risking their lives to protect the others — and to learn, just maybe, the secret of Summertide and the Builders…

The search for the legendary Builders results in the reemergence of an ancient race of galactic marauders who must be stopped before they reconquer the world in this sequel to Summertide and Divergence

The discovery of an ancient alien technology known as the Artifacts enables the human race to jump from galaxy to galaxy, but when a strange new Artifact emerges and changes all the other Artifacts, chaos ensues

A few years after the disappearance of the mysterious Builder Artifacts salted throughout the inhabited regions of the universe, a new phenomenon appears in the unexplored Sagittarian Arm of the galaxy, a force with the power to destroy planets. Capt. Hans Rebka and his team of galactic troubleshooters travel to the threatened Marglot system only to find themselves directly in the path of destruction
