As you may know, as part of my CSR for the MUM project.
I along with Tilo and Claus Werner have produced a childrens book.
It is available on Amazon.
This link gives you access to the story behind the story.
It also has links to Amazon/other retail outlets for the book.
The book is available for free download on Amazon
at the beginning of each month. A free download historically
generates $2 USA for the charity ROKPA.
100% of the royalty payments are paid DIRECTLY to the charity.
Personally, I much prefer the physical book.
The download is not particularly great. Get one for free, and buy the physical book!
