I'm starting a thread for anyone using The Mystery of History. I want to purchase this either this year or in a couple of years....here's my situation. I have a newly 5yo dd and a newly 8yo ds. I know the 8yo would love this curriculum, but I am concerned about how much the 5yo will pick up right now and can it be repeated in a few years and still be a good program for my then 11 or 12 year old boy? My other option is to do some American history with read-alouds instead and hold off on the ancient history if it will be more timely later. Also, does anyone now if the author will have the second edition ready for next year, and how many volumes will be included in the series? I want to do this soooo bad! I just want to make sure that my timing will be appropriate.
