Born of Fury by Sherrilyn Kenyon
The war is on between Sentella and the League of the Ichidian Universe. Huak is part of one of the five founding families of the Sentella. He is sent to a foreign planet with his niece and nephew to partake in the tradition of his people to have the young Andarian become adults through survival… that is, if the Assassin sent by the League doesn’t kill them before all of the wild monsters that inhabit the planet get to them first. All forms of communication are cut off, Hauk is haunted by his past, and his will to survive is only for the sake of his niece and nephew. Can they surviveon this foreign planet or will the war happening between these two peoples be the end of Hauk and his family?
