Cory Doctorow (Little Brother) has a new novel called Makers, and like his previous novels, he's offering it as a free download on his website under a creative commons license. From Boing Boing:

As with all my previous novels, the whole book is available as a free, Creative Commons download, under a NonCommercial-ShareAlike license that allows you to remix it to your heart's content and share the book and your mixes noncommercially. And as with my last two books, I've created a unique donations program that connects generous people with schools, universities, libraries, shelters, prisons and other cash-strapped institutions.

You can download the book and find out how to donate it to worthy institutions at Doctorow's website. I haven't read it yet, but I LOVED Little Brother, so I can't wait!
