The Ghost of Avalanche Mountain (Goldstone Trilogy) 1st edition

I got the goldstone at a time when I needed something special. I wore it for years, never thinking it was more than a beautiful pendant and a link to the past. Later I learned the the goldstone is also a link to the future. Wear it at night, and you'll see what lies ahead. With these words, Aunt Jo gives Ashley the beautiful goldstone necklace that has been in their family for nearly a century. Ashley is immediately enchanted by the magic of the stone, and can hardly wait to dream on it to see what her future holds. But fate has brought Ashley much more than the goldstone. When she wears her gift, a presence deep within the glacial mountains is awakened. A boy named Jonathan, who has transcended the bounds of time, begins to stalk her nights--and days. He, too, dreams of the future and has foreseen the moment when he can reclaim the stone. But he know that he can only do so once Ashley has joined him in the space between life and death.
