I can't comment on any books, but to answer your question of Sweden, I wouldn't be surprised. Western Europe are often quite free when it comes to sexuality. I think England and the UK in general are quite late to the game. The Netherlands seem to get the most praise for freedom of sexuality, and freedom of other kinds too.I just read the first two books, too! I found it pretty clear, as well. The editor is the hinge of a vee and her husband is bisexual. I thought it was awesome how much detail the author put into the relationship. I wonder: is being poly more acceptable in Sweden? I have no idea, as I come from a small town in the US
