A 1991 cyberpunk novel, with a bunch of familiar early cyberpunk tropes -- "hackers", people connecting brains to computer networks, a computer program becoming sentient.

The story is a fun ride, although I didn't love the many surreal dream-like passages where she tries to convey the experience of brains connected to computers. I found it at times confusing, and the writing wasn't sharp or evocative enough to carry it through.
