My next novel, Little Brother, officially goes on sale today! In addition to the US print edition, there's a DRM-free audio edition (there're also forthcoming editions in the UK, Greece, Russia, France and Norway, with others pending) from Random House Audio. My deal with Random House is that they're absolutely not allowed to sell the book with DRM on it, which, sadly, means that Audible (the largest audiobook store in the world) won't carry it -- they insist on selling books with DRM, even when authors and publishers don't want it.
Instead, you can buy the audiobook from Zipidee, a retailer that Random House uses -- they have the spiffy embeddable Flash sales-object you see above (feel free to paste it into your own blog or whatnot), and there's also this static URL for those of you who can't use Flash.
The audiobook comes with my own sampling license: once you own it, you're free to take up to 30 minutes' worth of material from it and remix and then redistribute it as much as you like, provided that you do so on a noncommercial basis, make sure that it's clear that this is a remix and not the original, and make sure that you tell people where to find the original. This is in addition to all the fair use remixing that you're allowed to do without my permission (of course!).
I'll also be releasing (as always!) a free, Creative Commons-licensed version of the text of Little Brother, just as soon as I get back to London (I'm presently in Toronto, visiting my family with my newborn daughter). It'll likely be Monday or so -- there's a bunch of little clean-uppy things I need to do with the Little Brother distribution site that I need to be in my office with uninterrupted time to accomplish.
