it seems like some of the commenters here need to remember that people are entitled to their own opinions and beliefs. the basic premise of this book is no different than an individual choosing to be an atheist. if you’re offended by Christianity, just know that I’m not offended for your atheism, just sad for it.
that being said you do not need to be a Christian to understand or read this book, I found it an excellent thought process on the whole. in fact atheists might get more out of it than a Christian would.
I don’t want to be a spoiler and give too much away, but if you enjoyed infinite to any extent, I highly suggest this book, and even more so suggest you finish it. the same goes for atheists, if you choose not to listen to the whole story, are you really in a position to leave any kind of comment or thought for the next person?
