Price for the book on Amazon.de has been adjusted!
I still would definitely recommend buying the book on Blurb.com
https://www.blurb.com/b/11337236-other-civilizations
Blurb is located around the world so you can order the book from a Blurb-site nearer to your country and closer to your home address (SELECT the flag of the country you are in or select WORLD). It only takes Blurb less than 5 business days to produce the book and a couple of days to send it to you. AMAZON.DE has adjusted price to 46 Euro. Ordering directly at Blurb.com you pay about 37 Euro.
Just to let you know the price difference.
All the best
