Souls of the Stones Omnibus Edition — Kelly Walker

When Emariya Warren learns enemy forces have captured her father, she'll do anything to save him. Anything. Even marry a mysterious prince she knows nothing about in order to rally the strength to arrange a rescue. During her journey to Torian's foreign castle, Emariya comes face to face with her mother's killers--and a deadly secret. Not only does Emariya possess a powerful but unexpected magical gift. So does the prince she's promised to marry, and an ominous prophecy has warned their gifts must never be combined. If she breaks her promise to marry Torian, she won't be able to save her father and if she keeps it, she may bring a curse upon everything she holds dear. Determining which choice is best won't be easy, but when she meets the gorgeous prince who may desire more than just her heart, she realizes she will have to fight just to have a choice at all.
