Showing Promises To Keep by Heather Kuehl

Starlette is on a mission, and nothing will get in her way…
Starlette DeFore knows that her father is alive, even though her family buried him ten years ago. When a faerie confirms this she travels to Charleston, South Carolina to hunt down Sivad Night, the only person to have ever escaped from the hands of a powerful sorceress, the Dark Lady Dreashae. With help from a witch, Stalette travels into Verella, a fantasy realm filled with centaurs, dragons and magic. She is very close to finding her father, but first must defeat Dreashae.

Will Starlette, a mere mortal, have the strength needed to finish her quest and save her father?
