I finished reading (or listening since it was an audio book) to Larry Niven and Jerry Pournelle's Mote in God's Eye.
And I was wondering if there is a suggested order to read their books? Plain chronological or is there any other suggestion?
Most Niven & Pournelle collaborations are stand-alones, and can be read in any order.
They do have some works with sequels. In almost all cases, the first book was originally stand-alone, and the sequel came out years later.
Jerry also wrote a number of works leading up to Mote in his CoDominium/Empire of Man universe. Most of them are part of the Falkenberg’s Legion saga, which is set roughly 900 years before Mote:
Prince of Sparta
Note: The book Falkenberg’s Legion is a compilation of West of Honor and The Mercenary. The book The Prince is a compilation of the entire saga.
King David’s Spaceship takes place more or less simultaneously with The Mote in God’s Eye, but is pretty much stand-alone.
