The fae world below has been taken over by an evil queen. The human childe changling has escaped to the surface to find the fey who replaced him. Edmond is just trying to live a normal life despite his growing magic. He is not thrilled when the changling appears. When they are attacked by the evil queen's minions, he agrees to help take back the court. They are followed below by their human sister and assisted by the golem Whick. 

This was a fun adventure story. I liked seeing the different perspectives of the human and the fey. There were also some interesting ways in which the human and fae worlds intersected that was pretty creative. I loved that the sister was so accepting and loving of both of her brothers.
