Another fabulously enjoyable science fiction adventure from qntm. Like their other novels, it does a tremendous job of exploring the implications and consequences of big science fiction concepts.
In this case, it's a story of human superheroes, whose powers derive from beings-beyond-comprehension, from the high-dimensional multiverse, the Structure, within which our paltry three-plus-one spacetime is naught but an embedded decal. Their struggles rewrite the fundamental physics of our universe, to fashion it into an inescapable trap, denying humanity access to advanced sciences, and to communion with the higher levels of the Structure. Loved it.
For those like me with an epub fetish, you can buy Fine Structure in many formats, including Amazon links, EPUBs, or free-to-read online, at the author's site.
