Welcome to MR, Heikki Hietala.
You may want to go to the Introduce Yourself forum
and start a thread so more members will be able to great you.
Your book sounds very interesting, but I don't have a Kindle (I have a Sony).
We are a worldwide forum of many devices and members. Will you be publishing in the ePub format or on smashwords so those of us without Kindles may purchase your book?
Have fun in the forums and ask if you have questions.
