Descendant of the Crane

I don't know what to say. This book got me confused and not in a good way.

It had a lot of good points - intricate writing, more or less good plot and even one surprising twist (the second one was not that surprising).

However, the ending crossed it all out. Considering that the book is supposed to be a stand-alone, it was so disappointing. The book ended with nothing. Literally nothing.

In the answers to questions, the author said that there may or may not be companion novels. I prefer one decent finale in the book that I've read to the one in possible companions.
