It also got me interested in the 30 years war which i didnt realise was possibly even bloodier period than WW1 and 2 in europe for the populations impacted.
He has another series in same premise with a modern cruise ship going back to ancient greek times, not as good as this series tho'.
if anyone else has any other recommendations in same genre of time travel and re-booting up civilisation it be great to hear! I always found the genre interesting since Jules Verne's Mysterious Island https://www.goodreads.com/book/show/32831.The_Mysterious_Isl...
The short story "The Man Who Came Early" by Poul Anderson touches on that theme as well. A soldier is transported back to Iceland of about the year 900 AD.
David Drake wrote a sort of prequel to "Lest Darkness Fall" called "To Bring the Light", with an imperial Roman woman transported back to the founding of Rome. Drake's personal experiences increase the realism of his writing, IMO.
He also wrote "Ranks of Bronze" which is sort of the reverse idea, a Roman Legion kidnapped by aliens for preindustrial warfare. Absolutely worth a read, and an interesting counterpoint to most of the 'bringing civilization to the barbarians' narrative these stories normally follow.
H. Beam Piper did a bunch too, check out "Lord Kalvan of Otherwhen" if you can find it.
Yes, Stirling's Nantucket series is a good example. Loosely also his Emberverse (basically the flip side of the Nantucket series) although I lost interest as I often do with long-running series. Lucifer's Hammer by Niven and Pournelle. A Connecticut Yankee in King Arthur's Court is probably the classic of the genre (Mark Twain).
Most of these books are probably overly optimistic about what one or a small group of smart people who just happen to have to right skill sets could accomplish in such a situation with very limited supply chains.
Flint was involved in the Belisarius series (along with David Drake), and Safehold is basically Weber's "reboot" of one of the books in his "Armageddon Moon" series.
If you liked 1632 you will probably like these as they're in a similar vein
There seemed to be a lot of questions about what would happen if the supply chain broke today... this series explores that issue in a deep way.
