The Eschaton Sequence is a trilogy of three Science Fiction novels: The Other End of Time (1996), The Siege of Eternity (1997), and The Far Shore of Time (1999).
Essentially, this is a First Contact story as a group of humans are sent to investigate alien signals warning of the destruction of Earth by the malevolent Horch. The group of astronomers, led by Dan Dannerman of the Bureau of National Investigation, are taken prisoner by aliens.
Pohl uses many of the tricks he’s developed in past novels: alien technology, clones, bureaucratic bumbling, and tricky humans.
I’ve been reading Frederik Pohl since the early 1960s beginning with Drunkard’s Walk (the nude on the cover may have influenced my choice). I also enjoyed the Pohl and Kornbluth collaborations.
I enjoyed The Eschaton Sequence but be aware it’s 801 pages long with some tedious chapters. GRADE: B- (for all three novels)
