you CAN read the LaVeyan Satanic Bible but you should remember it has nothing to do with Satan! Satanism is only the name he gave to his atheistic philosophy because satan symbolises individuality and freedom. It's like calling my dog ''cat''. It doesn't mean he's a cat. It just means it's called ''cat''.
So do as you please, but it's not something that has to do with our religion.
