Read More Irish Authors Challenge - hosted by mh_books

I once was a member of an Irish Goodreads group were an argument broke out whether speculative fiction (fantasy and science fiction) should be read as part of the group. I believe they should be ! So a book that would be considered speculative fiction by an Irish Author.
If you don't like Genre fiction maybe try a book that has a title that sounds like it could be speculative fiction.
