Zaregoto Series could be one of the best works that I have read in my life. It mix a lot of elements and tools that make the story so enjoyable and intriguing. I've read the first 5 novels that are available in english/spanish in internet, and I'm desperately waiting for the rest. The first volume is highly entertaining, since the beginning when they showed the scenary and the first death. Anyway, You can check the anime if you don't want to read this volume, although reading is the best option. The second volume is my favorite of all the series, and probable my second one in mypersonal list of all kind of books (first is Murder on the Orient Express of Agatha Christie). This book tells the story after the crow island, when we know in depth the personality of the main protagonist "Li-chan" and his misadventures both in the university and in his daily life.

And the other three are the same in many ways, a mix of emotions, sensations and obviusly non sense and despair, but how can i say it? You can only know what I'm talking about if you read the series (I'm a little tired to relate them). If you can watch and read zaregoto, please do it. You can't loss this whole series.
