A Note About Our Book Ideas

It goes without saying that there are a variety of choices for reading materials these days, and families will have different standards.

Just as in our handbook’s reading challenge, the books you’ll find listed here are ones that members of our team have read, added to their “I want to read this” list or have had recommended to them. Even among our team, there is a wide range of titles our families would find acceptable. Some of us find fantasy objectionable and skip books that obscure a solid Christian worldview, but will gladly read a scary adventure story that other families would opt out of. Others consider those fantasy titles to be an exciting addition and worthy of much discussion. We’ve opted to include titles with abandon, knowing that you will be able to determine if they are a good fit for your family.

So this is not a “Timberdoodle would sell these books if we could” list. We can’t vouch for each of the titles, and we certainly can’t know which ones are a good fit for your particular family. Nevertheless we are providing this list to give you ideas to be used as a starting point. As always, we highly recommend reviewing the books yourself before turning them over to your children.
