The Hidden Queen (Anghara Kir Hama #1)

the long version

The life Anghara knows has ended; everyone she loved is dead or doomed. And now she must flee far from her home or die at the hands of her half-brother Sif. A defenseless child is adrift in an unfamiliar world, pursued by the minions of a false king whose brutality knows no bounds. But Anghara has a great destiny that reaches beyond the borders of the troubled realm she must one day rule -- and a miraculous gift to be awakened in secret and fortified in a distant desert land at once beautiful, mysterious, and perilous: an awesome and frightening power called Sight.
