Changer of Days — Alma Alexander

The child Anghara Kir Hama was forced to flee the kingdom she rightfully ruled, escaping the murderous wrath of her brother, the usurper, who would see her dead to secure the throne. But her years spent in a strange desert land -- honing the miraculous power called Sight -- have forever changed the young queen. And now it is time to claim what is hers.

But treachery greets Anghara upon her return to a realm suffering under the cruelty of the bloodthirsty tyrant Sif. In the dungeons of her enemy, she awaits an inevitable death, robbed of the gift that set her apart from all others. Yet those who have sworn to defend her will not rest until their cherished queen is safe, including one whose noble heart belongs to her alone. For young Anghara's remarkable destiny is greater than crowns and countries -- greater even than the fearsome Old Gods who must stand down to make way for the Changer of Days.
