Cal, a hungry sixteen-year-old sick of mining the sand, wants to fit in and make his ma proud, but instead, his violent tendencies bring shame. And the truth. He's the son of a Draco Sang. Carriers of the Dragon's blood, the Draco Sang transform into half human half beast as they mature into adults. And if Cal can't control the dark impulses of his dragon blood, he'll grow into a man-beast-and he'll be hunted.
Ferth, son of a Draco Sang chief and last of his class to grow claws, needs to prove his worth to his father, or he'll be sent to the slave house. Hiding his human heart, he joins the army headed south to conquer the fertile human lands.
Neither brother feels they belong. Cal is human, fighting against becoming a beastly Draco Sang, while Ferth is struggling to push back his humanity and transform into a worthy Draco warrior.
Before ever meeting in open battle, Ferth is sent to kill Cal. But when he learns they are brothers, he must decide which loyalty is stronger, blood or country. And whether to finally give in to his humanity.
