Veins of gold

"Abandoned by their father for the gold rush, Gentry and her siblings labor to survive alone in the inhospitable west. When bizarre natural disasters begin wreaking havoc on the land, Gentry discovers a world of magic. Desperate for help, she accepts aid from a mysterious stranger. Winn not only sees the magic, but controls its hunger by feeding it gold--the very thing Gentry's father left to acquire. But the earth's unrest only grows worse, and Gentry's fear leads her to a terrible choice: marry a wealthy man she does not love, or trust in Winn's unpredictable power to save her family."--Amazon.com.
