A lie can only last for so long… When Amelia learns the dark truth behind the Vilnarian Empire’s schemes, she must decide once and for all which path to take. Will she escape to the safety and warmth of her homeland, or take the path leading her back into danger—back to the charming Emperor Kyvir. In a world of spies, false identities, and kingdoms at war, Amelia can no longer trust anyone…not even herself. Will Amelia succeed in toppling a corrupt empire bent on conquest, or will she lose everything that she’s ever loved? A Traitor's Vow is the exciting sequel to The Librarian's Ruse, and the second book of the Adventures in Eldnaire series.
