The problem with that book is some people can handle it all at once and others it puts them into shock. You have to realize that everything a person believes, values and think is the only way to god comes crashing down in one book.
While I could handle it, it definitely put me in a funk for a few months after reading it just trying to cope. I could only imagine someone that is more emotional. It also depends how "in" they are at the time of reading.
