Ahoy there mateys! I loved this novella.  It follows Ester and her giant roc Zahra.  The story is primarily one of relationships - both those of the riders and their birds.  But make no mistake, the rocs are wild animals and dangerous.  I loved the look into the life of the Royal Mews.  I loved getting Ester's backstory.  I loved Ester's growing friendships with other riders.  I loved the world building and descriptions of the kingdoms monsters.  I also rather enjoyed the ending though it took me aback at first.  In general, I feel this novel was the perfect length for the plot.  Arrr!
