Kas

Most teenagers don't have a voice talking in their heads, but that's pretty normal for Kas. It's been there her whole life, giving her directions, keeping her from harm. When the voice advises against the family picnic in the mountains, she's sure there's a reason, but convincing her mom is another matter.
While in the mountains, Kas accidentally stumbles on a gateway to another dimension. Almost immediately, her life is in peril. From a disembodied man known only as Milord and a hoard of hooded men who want her soul, she doesn't know who to trust in this strange place where dreams become reality.
As Kas learns more about who she is and how she came to the Waymeet of Worlds, it becomes clear that someone is lying to her. But is it the voice she's known her whole life or the new friends she finds in Milord's castle. Choosing the wrong people to trust could cost her soul and prevent her from fulfilling her destiny.
