The Necklace of Oaths

When common-born Seraphina Vale becomes a princess overnight, she believes the greatest challenge will be learning court etiquette.
She is wrong.
On the day her mother marries the kings, Seraphina is gifted an ancient necklace one that binds itself to her soul and awakens long-dormant magic. As whispers of rebellion spread and a fallen regent returns from exile, Seraphina is forced into a war she never chose.
With the kingdom under siege, enemies closing in, and her family torn between blood and loyalty, Seraphina must decide what kind of ruler she will before the necklace decides for her.
