Crown Princess Ioanna of Xytae has kept her truthsayer blessing a secret for twenty years. In any other nation, her powerful magic would be cause for celebration. But Xytae’s patron is the war goddess Reygmadra, and the future empress is expected to be a brutal warrior.
Reserved and peaceful by nature, Ioanna knows the court sees her as a disappointment. She does her best to assuage their worries every day, working quietly beside her mother to keep the empire running while her father is away at war. But when news of the emperor’s untimely death reaches the capital, Ioanna finds herself ousted by her younger sister Netheia, who has the war magic Ioanna lacks.
Princess Vitaliya of Vesolda has come to Xytae to avoid her father’s upcoming wedding, which she sees as an affront to her mother’s memory. Vitaliya has absolutely no interest in politics or power struggles and intends to spend her time attending parties and embarrassing her family. But when she saves Ioanna’s life during Netheia’s coup, the two are forced to flee the capital together.
Despite their circumstances, Vitaliya enjoys travelling with Ioanna and realizes that the future empress’s shy and secretive nature is the result of her unhappy childhood. Ioanna is equally unaccustomed to being in the company of one as earnest and straightforward as Vitaliya, for she has spent her life surrounded by ambitious and cutthroat nobles.
Ioanna cannot allow her sister to continue their father’s legacy, and plots to rally supporters to her side so she can interrupt Netheia’s coronation. Vitaliya knows she ought to leave Xytae before the nation is ripped apart by civil war but finds she is unwilling to abandon Ioanna. But Ioanna’s enemies are always watching…and they’ve realized that Vitaliya is a weakness to be exploited.
