From Publishers Weekly
This promising first installment of the projected Heritage Universe series stands on its own, even though many threads are left dangling. In A.D. 6219, mankind has spread across the galaxy, discovering two other star-traveling races and 1236 artifacts, from three to 10 million years old, left by beings known as the Builders. Now one person from each race has detected clues that might lead to another artifact, or perhaps even to the Builders themselves. Conflicts among the three races fuel most of the plot. Wishing to keep the findings secret, their respective governments provide only covert aid--a device Sheffield ( Between the Strokes of Night ) may have employed to justify the small size of his cast, six members of which will clearly be the main characters in future series volumes.

While the twin planets of Opal and Quake prepare for the violent season of Summertide, two planetary administrators investigate the reasons behind a tenacious group of visitors' sudden interest in the ancient artifact that serves as an "umbilical" connection between the two worlds. Political intrigue, mystery, and fast-paced action highlight this hard sf novel, the first in a series by the author of Proteus Unbound. For most sf collections.
