The ending left a bad taste in my mouth. I was expecting so much more, I could even live with fucking quadruplets being a thing, why not. But this supernatural deus ex machina shit? Come on! That just sucks.
The story had so much pull, there was mystery, potential romance for the MC. And then it all fell flat on the side. Why couldn't the author just take this, do minor changes to the plot and completely rework the ending into something more adequate?! Sigh...
