The Broken Heirlooms

Aelwyn, the greatest of the five nations, is on the brink of collapse. It's lifeblood and its magic had been weakened, and so has the land. People blame the Royal Family, believing they are paying for a curse they started years ago.
Lyaenor O'Dara is no longer the spirited girl who grew up in the palace halls. After years of training far from it, she has become a Warden: a cold, elite protector who was stripped of her past to serve a higher purpose. But when a desperate letter from Queen Naryssa arrives, Lyaenor is forced to break her exile and return to the heart of the kingdom she once called home.
She's expected to protect the future king, without knowing that he is no more than someone she swore never to see again.
