Book 1 of the Blood for Blood series. 

In a world where men and women teleport using air, dirt, and water... 

Kidnapped as an infant, Hakon is raised by the earth-empowered Terra people. Considered less than beasts, the clawed-hand warriors plot revenge against the air-empowered Alem that invaded their land centuries before. 

Hakon grows up with the knowledge that he is an Alem prince, tempered by the love he feels for the family that raised him. 

While Hakon tries to find peace between two warring peoples, his sister Kara rises from the hidden role of handmaid to the public role of princess. All she knows has changed, especially her relationships with those she once considered friends. 

Both Kara and Hakon must find a way to bring peace to the violent struggles over the land before everything they've ever loved is burned to the ground in front of them.
