Dear Sargamcola, there are no holy book for atheists or rationalists. These books are exposing the religions for what they are! You cannot counter the arguments of the religious zealots without knowing what is what. Though I do not believe in the dogmas of any religion, I have read the Bible, the Koran, Ramayana, Mahabharata, and parts of vedas and scriptures of other religions to understand what exactly they preach. I have not found any of them even remotely based on science or technology. So all the so-called holy books and the corresponding gods have outlived their utility.
