Cornerstone — Kelly Walker

In a world comprised of three rival kingdoms as different from each other as the families that rule them, Emariya Warren is unique in being a daughter of not one but two of the ruling families. Sixteen years ago, Emariya narrowly escaped dying on their cold estate floor beside her mother. Now, after learning her father has been captured, Emariya makes the desperate decision to follow in her mother's ill-fated footsteps and journey to marry the prince of a rival land, Torian Ahlen. But when Emariya discovers the secrets of the three families and an ominous prophecy warning the three bloodlines must never be combined, she begins to fear the handsome prince waiting for her may desire more than to steal her heart.
