"It is not enough to simply teach children to read; we have to give them something worth reading. Something that will stretch their imaginations—something that will help them make sense of their own lives and encourage them to reach out toward people whose lives are quite different from their own." —Katherine Patterson
Junior High is perhaps the hardest age group to find clean, fun, and engaging books. Over the years I've read plenty of books in that age group and have often been disgusted by their contents. Reading good books at an early age is essential. It teaches children morals, forms their minds and strengthens their imaginations.
