Two friends learn how quickly life can change when they go from living lives of luxury to being the most wanted fugitives in the land. When assassins threaten Princess Fi's life, her foster sister Erryn summons cursed beasts to save her. Branded a heathen, Erryn escapes the guards ordered to kill her and flees for her life. When she hears about a faraway temple that may reveal why she has summoning powers, she sets out on the long journey to reach it. But Erryn's pampered life doesn't serve her well in the wild. Bounty hunters and guards become the least of her worries. Back at the castle, Fi tries to carry on with her life. But then her father is assassinated, and Fi is framed for the crime. With the help of those loyal to her, she escapes from prison and searches for Erryn, hoping to enlist her aid in reclaiming the throne. But the outside world isn't kind to treacherous princesses. Fi's quest to prove her innocence leads to another cage, one that has her wishing she was back in a prison cell.
