Hi dmaline. I wouldn't recommend any books, not because I don't like books, but because the best way to learn is by trying things out. Once you've done a few tutorials, the first things you should do is find the best-looking site you can, and try to replicate it in Photoshop. This is the way I learned. It took a while, but it's not something I could have learned from a book.
