Personally, I would say don’t waste your time.
I wasn’t really interested in the book, but had to see what all the hype was about. Now, I am a voracious reader and read a wide range of different genres so that should clarify that it wasn’t just the “type” of book it was.
I am a Christian, and not really offended, just bemused by all the preposterous ramblings about the “sacred feminine”, etc. Ridiculous. Anyone who has read the Bible knows that women played a large role in Christianity.
But, more than that, the book was just…nothing. Nora Roberts, Mary Higgins Clark, and Karen Robards (to name a few) have put out romance/mystery books that are more entertaining and have better plot twists than this one, IMHO.
So, my advice would be, if you really want to satisfy your curiosity about all the fuss, pick a day when you are TOTALLY bored and have nothing better at all to do, and then start it and see what you think.
Again, JMHO.
