Thank you so much, Gurpreet! And sorry for not replying to this before now. That is unforgivable! I have just updated it, and there might be some new nuances that I have learned since that time. I have also published book two in the same series. You can find them here: https://geni.us/VikingPI1

Have you written the article yet? I would love to read it!

Again, sorry for the unprecedented late reply!
