In a world split in two, sisters Nara & Osha may have the power to bring it back together, if they can uncover the hidden truth… Isfalk is divided into two classes – the Branded, who are vulnerable to disease, and the Pure, who are bigger, stronger and immune. Orphaned twins Nara and Osha are sequestered in the citadel, where their unbranded skin entitles them to a life of privilege, but as precious breeding stock. Nara itches to escape her confines and return to the wilds of the Fornwood where she and her sister grew up, but when she is forced to run, she discovers there's much more at stake than her own life. The Branded are on the rise, and the girls are caught up in prophecies that foretell of a savior who can realign the world. Forced to accept the help of a mysterious southern Brand known only as the Wrangler, Nara discovers the latent power lying dormant in her uncanny abilities that she's had since childhood. But in a world where women are traded as commodities, who can she trust in the lands beyond the Fornwood? And why does the Wrangler seem to know more about her life than she does? Two sisters without a past hold the weight of the future in their hands.
