Humans and aliens gather at twin worlds linked by an ancient Builder artifact to witness an extraordinary tidal event. As Summertide approaches, their competing purposes converge around structures left by a vanished civilization whose technology remains dangerously misunderstood.

After Summertide transforms the world of Quake, the search for the mysterious Builders gains new urgency. The people caught in the planetary upheaval move closer to understanding the vanished creators of immense artifacts scattered across inhabited space.

An expedition accidentally releases members of the supposedly extinct Zardalu, former enslavers of whole civilizations. With no one willing to believe the danger, Darya Lang and her companions must hunt them down while confronting the Builders' hidden purposes.

An ancient transport network connects humanity to artifacts left by the vanished Builders. When a new structure appears and older ones begin changing, human and alien investigators set out to learn what has awakened before its effects become catastrophic.

Hans Rebka and his human and alien companions face a threat beyond the mysteries they have already solved. A force begins destroying entire stellar systems, forcing the group into another attempt to preserve the galaxy from annihilation.
