Air Ferrets Aloft

A light read. Would appeal to kids who are interested in planes, since there is some detailed explanation on the pilots job. I think it might be great for those just getting old enough to be wanting a series.
Bach does include some of his favorite philosophy in a way that blends with the story, not preachy, which I consider a good thing. I'd like my grandkids to be reinforced in listening to their "higher truth". Although I'm not sure if the romance angle would be boring to young kids--but, really, 2 ferrets aren't going to get too romantic.
I always enjoy getting reminded of destiny, guidance by angels, and keeping open to love (tho I limit my Bach reading to less than once/yr so I don't get overdosed).

A standard children's book set up with adult themes. This is becoming pretty common. But Bach goes further by making the book of the shape, size, and length (and with illustrations) of a child's book.
The characters perform adult jobs and have thoughts and feelings with all the ambiguity and shades of grey and conflicting desires covering the past, present, and future that a child (by lack of experience) can't hope to really appreciate.
Females are important and equal characters in these books, so that's a bright spot.

Bach's Ferret Chronicles detail the lives of animals who go out of their way to help others. Teamwork and self-worth are strong messages that shine through in these delightful books. Any dreamer is sure to appreciate these little gems.
