I loved the first two books and didn't want to believe that this was not as good, but unfortunately it is true.
This is the story of Nicias the son of the two renegade falcons of the first two books and his struggle with his awakening magic.
He's forced to go to Anhmik or die. On Anhmik he's faced with his grandmother who is plotting to make him stay and become her heir since she failed to coerce his father, but others, those locked in a kind of asylum for crazy falcons, are trying to "help" him...
The story is not as interesting as that of the previous books: it draggs and has made me yawn a few times. I was not so interested in what happens to Nicias, even if he seemed like a nice guy.
When the end came I was like: OK it has ended... and nothing more.
