I am grateful to the author for writing such a wonderful book. I couldn't drop the book until i was done. Though the ending was as open as the sky, i felt it ended well and doesn't need a sequel. An exquisite dish like this needs no dessert. 
 The only fault i found in the book was the genre it is advertised as. The only element of fantasy i found in the book was that there are goblins and elves. Even the goblins are not what a fantasy dictionary would describe 'fantasy' as e.g goblins are predominantly short but the great avar for example is 6 ft 5 in. The book is basically about imperial court and racism. 
 But nonetheless the book is one of the best book i have read till date. Kind of inspires me to want to be in a position of great power.
