Assuming you haven’t been here long (and are unwilling to click through the Deathlands tag): post-apocalyptic 22nd Century gun porn with teleporters and whiffs of Seven Samurai, in episodic format, series approximately 100 books in length. Okay? Okay.
Since I’m still reading them, it’s probably time to stop being surprised by how compelling they are, or at least to stop mentioning it every time. The real problem is that without that or the setting summary, and without massive spoilers, it’s hard to say much of a much. Plausibly, I should not concern myself with spoilers regarding a 25 year old men’s adventure series that nobody besides me is going to read, but it’s hard to think that way. The result of all of this being, there’s maybe a sentence, tops, I can put together to explain any given book.
In the case of Seedling, Ryan Cawdor and company stumble out of the latest abandoned secret government teleport installation into uptown Manhattan (or technically probably Queens, but whatever), where they discover the biggest collection of pre-nuke hardware and memorabilia any of them have ever seen, an unexpected mutant army, the expected levels of treachery and general Deathlands deadliness[1], and a deviously clever use of the book’s title.
[1] After all, it’s not named that because you’d want to buy into the timeshare.[2]
[2] Okay, fine, two sentences. But only barely.
