Publisher's Summary

When a human team is sent to scout a few hundred light-years in front of the death wave, it encounters a civilization far in advance of our own, a civilization of machine intelligences.These sentient, intelligent machines have existed for eons and have survived earlier "death waves" - gamma-ray bursts from the core of the galaxy. They are totally self-sufficient, completely certain that the death wave cannot harm them, and utterly uninterested in helping to save other civilizations, whether organic or machine.
But now that the humans have discovered them, they refuse to allow them to leave their planet, reasoning that other humans will inevitably follow if they learn of their existence.

amazing end to a series

I had a little difficulty getting started but once I got going I couldn't stop. 😊 as always Ben Bova wrote a thought provoking and beautiful story, and Stefan Rudnicki brought the book to life with perfec t narration.

Excellent Series, Gets Better with Each Book

Ben Bova, winner of 7 Hugos, founding fiction editor of Omni Magazine, and succeeding Editor of Analog, following John Campbell. No one does hard science fiction like Mister Bova. This series concerns attempts to save intelligent life. The characters and the story are very real. My only niggles is... "Why couldn't the book be longer?" I didn't want to leave.
