DawnSinger by Janalyn Voigt

The High Queen is dying… At the royal summons, Shae mounts a wingabeast and soars through the air to the high hold of Faeraven, where all is not as it seems. Visions warn her of danger, and a dark soul touches hers in the night. When she encounters an attractive but disturbing musician, her wayward heart awakens. But then there is Kai, a guardian of Faeraven and of Shae. Secrets bind him to her, and her safety lies at the center of every decision he makes. On a desperate journey fraught with peril and the unknown, they battle warlike garns, waevens, ferocious raptors, and the wraiths of their own regrets. Yet, they must endure the campaign long enough to release the DawnKing—and the salvation he offers—into a divided land. To prevail, each must learn that sometimes victory comes only through surrender.
