This book: a look at religion through the eyes of an atheist. A collection of poems, some serious some tongue in cheek, and some absolute blasphemy all designed to make you think to make you laugh or make you squirm do not read this if are religious or you will be offended. I did not write it for you but if you do read it you'll probably secretly enjoy it (after you've told me to burn in hell)
