Nadine in California Definitely Neuromancer good. Much less explication than in most YA fiction - readers have to tolerate ambiguity and figure it out as you go along.
Pep Feminist YA. Not in the same league as Neuromancer. Not even in the same league as the first Hunger Games, before that ran out of steam in the first sentence of the sequel.
Boris Budeck Neither. For YA it lacks a lot of explanation and chances for the reader to identify with one protagonist or several of them. Neuromancer was in a different class. It had better understanding of AI back then, than this book presents. It is proper sci-fi but definitely not hard sci-fi. It is space opera by the dimensions presented (=make everything freaking big). If the ideas presented add anything new to sci-fi is being debated.
Duncan Definitely proper space opera sci-fi. I don't there's anything that would preclude a young adult enjoying it, but with a viewpoint character who is several thousand years old it's definitely not a teen right of passage novel. There are a few children appearing as minor characters, but the first teenage major character doesn't appear until the second novel (referred to as a baby lieutenant) and her troubles aren't teen angst.
