Been reading the 163x Grantville alternate history series again, mostly because I wanted to. 1636: The Kremlin Games (authors Eric Flint, Gorg Huff, and Paula Goodlett) is a reasonably standalone novel in that series, and pretty engrossing. Russia’s always an interesting locale to put a speculative fiction story, not least because the place seems half-fantastic to Western readers anyway.
And so, adieu to The Day of the Triffids.
