The eye of the North (First edition.)

For fans of Karen Foxlee's Ophelia and the Marvelous Boy comes a rollicking debut about a young girl's adventures in the far reaches of the icy north.
 
When Emmeline's scientist parents mysteriously disappear, she finds herself heading for a safe house, where allies have pledged to protect her. But along the way, she is kidnapped by the villainous Doctor Siegfried Bauer, who is bound for the ice fields of Greenland. There he hopes to summon a mystical creature from the depths of the ancient glaciers, a creature said to be so powerful that whoever controls it can control the world. Unfortunately, Bauer isn't the only one determined to unleash the creature. The North Witch has laid claim to the mythical beast, too, and Emmeline-along with a scrappy stowaway named Thing-may be the only one with the power to save the world as we know it. Can Emmeline face one of the greatest legends of all time-and live to tell the tale?
