IMHO, much like the show it started spectacularly and spent its fuel too soon. I thoroughly enjoyed all 3 books, but there were definitely diminishing returns.

I will say even at its worst the trilogy is still better than the show (at least season 2)

tl;dr I've enjoyed them enough to buy them three times: once on kindle, once paperback, and again paperback as a set.... but I wouldn't rate them as 'high literature'.

I enjoyed them, though they do have flaws. They embody some of the firm tropes of cyberpunk--lots of sex, lots of grisly violence.

The first one is a fantastically done mystery, IMhO. The second and third do some marvelous worldbuilding.

In hindsight, they do remind me of The Expanse's writing a bit.
