Earthcore

A billion-dollar find, it waits for any company that can drill a world's record, three-mile-deep mine shaft. EarthCore is the company with the technology, the resources and the guts to go after the mother lode. Young executive Connell Kirkland is the company's driving force, pushing himself and those around him to uncover the massive treasure. But at three miles below the surface, where the rocks are so hot they burn bare skin, something has been waiting for centuries. Waiting ... and guarding. Kirkland and EarthCore are about to find out firsthand why this treasure has never been unearthed.
