From the publisher's website:
Traveling with a caravan they've built up from scratch over the course of the previous adventures, the heroes must navigate Golarion's frozen northern continent, the so-called "Crown of the World," to reach the distant land of Minkai on the other side of the planet. Along their journey, they learn that a monstrous entity is manipulating the blizzards and storms of the north, and unless she is defeated, the heroes may find themselves but the latest victim of the Hungry Storm.
A Pathfinder Roleplaying Game adventure for 7th-level characters, this volume continues the Jade Regent Adventure Path, a sweeping quest that takes the heroes from familiar territory in Varisia all the way across the ice fields of the Crown of the World to distant Tian Xia, the land of the Dragon Empires. This volume of Pathfinder Adventure Path also features an extensive gazetteer of the Crown of the World itself—Golarion's deadly north pole. Plus five new monsters of the frozen wastes in the Pathfinder Bestiary, new adventures of Varian Jeggare and Radovan (stars of the Pathfinder Tales novels Prince of Wolves and Master of Devils) in the Pathfinder’s Journal, and much more!
