Since I read this two book series back-to-back (in about a week and a half -- have been home sick), I figure it's okay to post about both of them together. I first read about Daemon on Joi's blog, and it sounded interesting enough to give a try.
[Semi-spoilers below. If you like cyberspace thrillers, you probably want to read these -- and could probably go without the following paragraphs.]
Anyway, I liked them both a lot -- probably Daemon a little more than Freedom (TM). They're sort of a mix between Fight Club and World of Warcraft, with maybe some Blade Runner thrown in -- lots of great ideas, lots of real implications of the technologies we all use constantly.
I will say that Daemon is the first novel I've ever read that included the syntax for a SQL injection attack on a web site -- but maybe that's just me. :-)
There's a lot of technical jargon for fiction, and lots of solid ideas about how technology works and what the future could hold -- and clearly researched extremely well.
Anyway, they're a fun couple of books -- if you're wondering what World of Warcraft grafted onto our own everyday world might look like, these are a great place to start. (That particular part gets a lot more pronounced in the second book.)
