Hidden Sanctuary (The Madonna Key, Book 6‪)‬

Tru Palmer's dowsing ability—she feels resources hidden in the earth—is a gift and a curse.

Years ago, she trusted the wrong people with her secret and was locked away. Now, in the Nubian desert on an oil-drilling job, Tru is struck by a powerful energy—one that brings visions of the past and tantalizes Tru with the promise that there may be women out there just like her.

When the source of the energy—a cache of ancient mosaic tiles—is stolen, Tru knows it is her destiny to get it back. But to do so, she must reveal her ability to the enigmatic man hired to report her every move to the very people who stole it—and who will kill to keep it.
