Literature and Books are always discounted at Schoolhouse Publishing!
Books are absolutely essential to your homeschool. Building a personal library seems almost inevitable when your life revolves around books, as it does during the homeschool season of life. You can always use your local library, but it is so nice to be able to pull that book off your own shelf, use it, mark it up, make notes in the margins, and refer back to it later. It's also comforting to know that the books on your own shelves espouse the standards and philosophy you hold to. When your kids pull out a book from your own personal library, you don't have to worry about whether or not you'll approve.
I have personally read many (not all) of the books we carry. I'll try to mention concerns we had (if any) and issues you may want to discuss with your homeschool students as they read the book. Because every family has different standards concerning what is acceptable (and those standards will most likely change as your student grows older, meaning I allow my older kids to read a "scary" book that I wouldn't allow a younger one to read, for example), please don't take my word alone about the appropriateness of a book. What I deem appropriate, you may not deem appropriate, and vice versa. Please read the books yourself and allow yourself to be led by the Holy Spirit as you set standards for literature in your family.
