Is there a lot of Christian content in this?
There is a verse every other week for copywork but other than that, not really. It uses narration so you can go where you want with that. All of her commentary is factual in nature, drawing the child's attention to the lesson at hand - capitalization, finding the noun, etc.
I have not been able to find her contact info. either. Sometimes when you buy something from Lulu the author will send you a greeting of sorts. I can't remember if she does or not.
Kimberly Garcia also has a copywork, dictation and narration program that is based on history - it includes historical narratives, poetry, myths/tales, and some original documents. It comes in two levels K-2 and 3-5. She has a great explanation of how to use CM methods in writing. http://www.writefromhistory.com/
I do plan to order level 3 the next lulu sale.
