Recs if you like The Builders...

Speculative (sci-fi, fantasy, horror etc.) novellas less than 200 pages long that are either standalone or read like a standalone story

One sitting. Thirty strange stories. Zero wasted pages.

Aka my favourite fantasy subgenre where we get both magic and intricate plannings to pull off something previously thought impossible (usually a break-in of some kind) and often everything then turns out to be much more complicated than previously thought

(For series I only included the first book of each)

Just animals doing people things
