I highly recommend Homebrewing for Dummies by Marty Nachel.
Even though it's one of those "Dummies" books, it gives a fantastic, easy to understand intro to the brewing process, the ingredients, and the equipment.
There is one piece of bad advice in that book. You MUST sterilize starter wort in a pressure cooker or autoclave if you plan to can it for later use. Botulinum toxin spores are not destroyed by simple boiling. You must use a pressure cooker to kill them and prevent them from taking hold and poisoning you. Granted, it does not happen often, but in the very rare event that it does, the consequences can be disastrous. Most books ignore yeast starters. At least this book addresses it. If you make your starter and use it right away, there is no problem. Again, the saving of starter wort without properly canning it is the only bad advice i've seen in the book and the rest of it is top notch.
