We found one (only one) at our local library (Edgewood) and DS4 loves it so far - we were thinking about getting more but a couple of things:

1. There seems to be hints of religious stuff sprinkled in there - does that happen a lot? How strenuously does the author push it?
2. They are SO expensive. Does anyone have any suggestions for finding any of the books on the cheap? We already looked on ebay, half.com and the like. I just want to magically discover a set someone isn't using at a garage sale or something...

I believe I have seen references to the Life of Fred books on this forum before. To the people who use them - do you like them? Do they work well for your DCs? Is there anything comparable (and cheaper? lol). To me, they remind a bit of Penrose, which DS loves as well.

Thanks so much!
