Crown of Midnight by Sarah J. Maas

I just finished an advanced reader's copy of Crown of Midnight and could not be more pleased!  Maas' first book Throne of Glass was amazing and I think this one is even better.  I love when that happens!  Celaena Sardothien has won the brutal contest to become King of Adarlan's personal assassin and has begun working towards her freedom by killing the King's enemies.  Although it would appear so, Celaena's loyalties do not lie with the King.  She has been faking her targets' deaths and helping them flee.  The King's next target must be killed for starting a resistance group against the King's "plans". Celaena feels she must find out more information about the resistance and these so called plans before acting.  All the while her relationship with the Captain of the Guard keeps growing, along with her intrigue of the Glass Castle's secrets.  I can definitely see this as the next big YA series.
