2019’s The Lost Puzzler is the first volume in Eyal Kless’ Tarakan Chronicles. It is a post-apocalyptic adventure.
The Catastrophe annihilated the Tarakans (who lived in high-tech enclaves on a distant-future Earth) and their enemies but it didn’t quite manage to kill every human on the planet. A few humans survived, scrounging what they can from the ruins. It’s a hard-scrabble life, full of unwanted adventure.
But adventures make good stories.
