The Emerald Glacier

Deep beneath Antarctica's Eriksen Glacier, a buried research station has gone silent—and a billion-dollar mineral discovery has made its crew a corporate liability. Former ice climber Rebecca Hamilton hasn't spoken to her brother Marcus in four years, but his frantic satellite call changes everything. Armed with a handpicked team of climbers and engineers, she must navigate lethal ice caves, outmaneuver ruthless mercenaries, and reach the trapped researchers before their oxygen runs out. Some fortunes are worth more than money.
