In my opinion these would be worth buying as paperback books: go to www.amazon.com and search there "tervola". There ought to be "read a sample" possibility there. On the other hand, one cannot be so sure of large amounts of info, kind of imoressions. The Finnish books are 1 450 pages, and of the English versions some are translations found in the internet, so I just don't know for sure. Anyway Finnish and English versions are different.
