Each parent can make that decision about the reading list for their own child, and not everyone will choose to make the same decisions that you or I would make. I recommend pre-reading books, and reading reviews on Amazon to determine if there is objectionable material. It's also important for children to know what's out there, while they are still in the safety of your own home, so they can discuss it with mom and dad, while they are in a nurturing environment. You know about this author, so you have read the book and formed your own opinions. When your child is old enough, they will also be able to read the book in order to learn, without it being devastating to their faith.
I would like to make a comment on the reading list. While most of the list is standard I have wondered how most followers of Christ can condone reading material that takes the Lord's name in vain and gratuitous profanity. Case in point, works of John Steinbeck, for example.
I just do not see the benefit of engaging such material even as they are touted as 'classics'. It breaks my heart to see the compromise of calling such works worthy of consideration when they clearly do not honor the call to focus on what is good.
I could, (and have.) elaborated more on our stance, but this is such a basic desire for one that would seek God's Word that it baffles me when some make an argument 'for' the works, whether books or movies, etc..
In any case, I just wanted to comment on this.
