This is a delightful book! I found it in the "Gender Studies" section of Mercer Street Books, which is not really where it belongs, because it's fiction, but it is definitely about gender! It's a star-crossed lovers story set in a world where everyone must register to use the internet, which means answering a series of questions, including questions about gender, so that their ads can be tailored (lol sounds familiar). However our two protagonists don't want to declare their genders; their genders are fluid, and they prefer staying anonymous, accessing the infobahn illegally, and running into each other on chat room after chatroom, where they have a wide variety of playful, tender, and creative cybersex. A lot of this book is chat transcripts, and a lot of those transcripts are sex. I have never met anyone who has read this book! I will keep talking about it until I get someone to read it.
