For questions about "A Time Odyssey", a trilogy of SciFi novels co-authored by Stephen Baxter and Arthur C. Clarke. They are an "orthoquel" to Clarke's famous "2001: A Space Odyssey" series, for which the [2001-a-space-odyssey] tag should be used.
A Time Odyssey is a trilogy of SciFi novels co-authored by Stephen Baxter and Arthur C. Clarke, comprised of Time's Eye, Sunstorm and Firstborn, published in 2000s.
The plot of the series revolves around powerful ancient aliens, "Firstborn". In order to prevent all other species from "wasting" too much energy (which would accelerate the inevitable entropic death of the Universe, thus rendering sentient life impossible at the end of the universe), they exterminate all the newer intelligent species they find. They preserve a record of these eradicated species by creating a new alternate pocket universe containing the species' homeworld in different time periods.
The "Time Odyssey series", while also dealing with the idea of an advanced intelligence policing the cosmos, is not a sequel or prequel to Clarke's earlier, famous "Space Odyssey" series of which "2001: A Space Odyssey" (1968) was first and most noted. Clarke called "Time Odyssey" an orthoquel, meaning that it’s thematically linked to his earlier work but not directly extrapolated from it.
Book 3, "Firstborn" was one of the last books that Sir Clarke published before his death in 2007, followed only by "The Last Theorem" with Pohl.
The third books is closed with a cliffhanger that leaves a clear impression of a sequel intention, but sadly Sir Clarke is no longer alive to collaborate on such.
