GNU/Linux Children's Book

Hello Everyone!

I noticed lately that there are not many books about GNU/Linux geared towards children. Most of the books I can find are either for software engineers or hackers who already have a solid understanding of computers and value ethical computing.

I've decided to write a children's book that revolves around the idea of sharing with friends and using GNU/Linux and free software as examples. I am almost finished writing a (very) rough draft and was wondering if any of you would find a book like this interesting? I plan to release the book under a libre license so that anyone can download and share it. After all, if the point of the book is sharing how would it look if I did not allow others to share my book??

Also have any of you written a book and had it published? I haven't researched any publishers yet because I'm not really able to afford too many fees at the moment, but I would love to one day sell actual hard copies of my book!
