I didn't read it, but the title sure bring me to the sypnosis.
Well, the infamous wikipedia summary. At first I am interested by the 'partly Cinderella inspired'.... but when I continued, it doesn't seemed like my preference of 'Cinderella inspiration'.

Now to think of it, I am not sure whether I should even share this shallow understanding from just the sypnosis. But since I typed it out... might as well post it. x.x And hey, I remember the days that I finished Harry Potter and the Prisoner of Azkaban in a day too. I am kind of envy that you are able to find story that captivated you like that, and also a bit of relief since I really do not have the time to spend my days reading like that.
