No Starch Press just posted a sample chapter for The Tangled Web. You can grab the PDF here and see what it's all about. The book itself should be available by November 15; you can also preorder on Amazon.
If you don't know what this is all about, you can also head over to the home page of the book; but the bottom line is that I think it's the first-ever reasonably detailed examination of the browser security model and its evolution through the years - and really, that's something you just need to know to develop modern web apps.
PS. It's apparently always April Fools' at Microsoft!
