Raybearer by Jordan Ifueko
'Only one thing is more powerful than a wish, and that is a purpose.'
Tarisai has always longed for the warmth of a family. She was raised in isolation by a mysterious, often absent mother known only as The Lady. The Lady sends her to the capital of the global empire of Aritsar to compete with other children to be chosen as one of the Crown Prince's Council of Eleven.
If she's picked, she'll be joined with the other Council members through the Ray, a bond deeper than blood. That closeness is irresistible to Tarisai, who has always wanted to belong somewhere. But The Lady has other ideas, including a magical wish that Tarisai is compelled to obey: kill the Crown Prince once she gains his trust.
Tarisai won't stand by and become someone's pawn - but is she strong enough to choose a different path for herself?
