During the Second World War, siblings Zakhar and Mila Blackwood are sent to stay at their grandparents’ secluded manor until the war ends. While exploring the old house, they discover a magical wardrobe that leads to Narnia—a land of talking beasts, ancient prophecies, and looming danger. After Mila becomes separated from her brother and falls into the hands of the White Witch, Zakhar joins Peter, Susan, Edmund, and Lucy in a desperate search across Narnia. With an ancient prophecy revealing that six children—not four—are destined to save the realm, the fate of Narnia may rest in the hands of the Blackwood siblings.
