Across the Sea of Suns. Furious Gulf.

These two books in the Gregory Benford Galactic Center series, especially Furious Gulf, feel to me like masterpieces in fiction.  Benford writes “hard” science fiction that is heavy in physics and science, some of which is a little fantastic and hard to believe, but it makes for great stories.  His idea that the galaxy would be dominated by mechanical life forms intolerant of biological life has a convincing feel to it.   These books are a wild ride that stretch the imagination as to what is possible.  I especially enjoyed listening to them on Audible, because the performance of the readers gives the stories extra flavor.
