To the north lies the mammoth Wall of ice and stone—a structure only as strong as those guarding it. There, Jon Snow, 998th Lord Commander of the Night’s Watch, will face his greatest challenge yet. For he has powerful foes not only within the Watch but also beyond, in the land of the creatures of ice.

And from all corners, bitter conflicts soon reignite, intimate betrayals are perpetrated, and a grand cast of outlaws and priests, soldiers and skinchangers, nobles and slaves, will face seemingly insurmountable obstacles. Some will fail, others will grow in the strength of darkness. But in a time of rising restlessness, the tides of destiny and politics will lead inevitably to the greatest dance of all. . . .

The world is only half made. What exists has been carved out amidst a war between two rival factions: the Line, paving the world with industry and claiming its residents as slaves; and the Gun, a cult of terror and violence that cripples the population with fear. The only hope at stopping them has seemingly disappeared--the Red Republic that once battled the Gun and the Line, and almost won. Now they're just a myth, a bedtime story parents tell their children, of hope.

To the west lies a vast, uncharted world, inhabited only by the legends of the immortal and powerful Hill People, who live at one with the earth and its elements. Liv Alverhyusen, a doctor of the new science of psychology, travels to the edge of the made world to a spiritually protected mental institution in order to study the minds of those broken by the Gun and the Line. In its rooms lies an old general of the Red Republic, a man whose shattered mind just may hold the secret to stopping the Gun and the Line. And either side will do anything to understand how.

Jayné Heller thinks of herself as a realist, until she discovers reality isn't quite what she thought it was. When her uncle Eric is murdered, Jayné travels to Denver to settle his estate, only to learn that it's all hers -- and vaster than she ever imagined. And along with properties across the world and an inexhaustible fortune, Eric left her a legacy of a different kind: his unfinished business with a cabal of wizards known as the Invisible College.

Led by the ruthless Randolph Coin, the Invisible College harnesses demon spirits for their own ends of power and domination. Jayné finds it difficult to believe magic and demons can even exist, let alone be responsible for the death of her uncle. But Coin sees Eric's heir as a threat to be eliminated by any means -- magical or mundane -- so Jayné had better start believing in something to save her own life.

Aided in her mission by a group of unlikely companions -- Aubrey, Eric's devastatingly attractive assistant; Ex, a former Jesuit with a lethal agenda; Midian, a two-hundred-year-old man who claims to be under a curse from Randolph Coin himself; and Chogyi Jake, a self-styled Buddhist with mystical abilities -- Jayné finds that her new reality is not only unexpected, but often unexplainable. And if she hopes to survive, she'll have to learn the new rules fast -- or break them completely....
