Exhausted from war, grieving the loss of his first rider, Dynami returns to Okyro uncertain what the future might hold. He gains a new rider and under S'Yrinim's steady hand, he heals and learns to enjoy life once more.

But life can be as dangerous in the courier service as it is on the Line, and not everyone will be as accepting of a hybrid as S'Yrinim is. Dynami is forced to choose between peace and duty, and his life may hang in the balance.
