The first book in a brand new fantasy series by Adrian Tchaikovsky. This is an ever popular coming-of-age story, in an epic fantasy setting featuring warfare, tribal loyalty, twisted politics and invasion. A young girl is estranged from her tribe, as her mother was from a despised rival clan. This is despite the fact that her father is chieftain. Her greatest secret is that she's gained powers from both factions. A child of two worlds, she must escape to survive. But even as her actions trigger war, a greater threat appears on the horizon, which will signal a battle to the death for all the tribes.
