I’ve read them all, but Count Zero and Mona Lisa Overdrive I haven’t read since the late 80s, so I don’t remember them well. Broadly, I think they were all worth reading. Count Zero was nominated for all the big SF awards, but I didn’t think Mona Lisa was as well received. I’m not sure I could even tell you the plots of them other than the second book has a lot about AIs, and the last one about online identities or something.
Yeah, in in my 60s, so old. When I was in my mid 20s, I was in a bad marriage and needed some escapism. One of my coworkers was a reviewer for Locus Magazine, which is a major SF publication. I asked him for recommendations, so he went with me to the bookstore and said “Try that one, that one, to and that one.” One of those first was Neuromancer. I chewed through them, and it became a routine to go to the bookstore with him.
I eventually got divorced, and didn’t need the escapism anymore. My reading went way down, maybe a few books a year. Now I’m heading towards retirement and I’ve been reading more than ever.
More detail than you wanted.
