In the cold, treacherous land of Vesimaa, children are stolen from their families by a cruel emperor, forced to undergo a horrific transformative procedure and serve in the army as magical fire-wielding soldiers. Pran and Oksana - both taken from their homeland at a young age - only have each other to hold onto in this heartless place. Pran dreams of one day rebelling against their oppressors and destroying the empire; Oksana only dreams of returning home and creating a peaceful life for them both. When they discover the emperor has a new, more terrible mission than ever for their kind, Pran and Oksana vow to escape his tyranny once and for all. But their methods and ideals differ drastically, driving a wedge between them. Worse still, they both soon find that the only way to defeat the monsters that subjugated them may be to become monsters themselves. As electrifying as it is heartbreaking, Sam Taylor's explosive fantasy debut is perfect for fans of the legend of Spartacus and An Ember in the Ashes.
