Every 100 years, the Witch Queen Baba Yaga returns to the nation of Irrisen to place a new daughter on the throne, but this time, something has gone wrong! Far to the south, an unseasonable winter cloaks the forest near the village of Heldren with summer snows. When the heroes venture into the wood in search of a missing noblewoman, they discover a magical portal to the frozen land of Irrisen, whose magical winter will soon engulf all of Golarion unless they can discover the fate of the otherworldly witch Baba Yaga, a quest that will take them through snowbound Irrisen to even stranger lands beyond. A Pathfinder Roleplaying Game adventure for 1st-level characters, The Snows of Summer kicks off the new Reign of Winter Adventure Path, and includes a gazetteer of the villages of Helgen and Waldsby, details on the cultural and magical legacies of Irrisen, and several new monsters in the Pathfinder Bestiary. Also, author Kevin Andre Murphy launches a new Pathfinder Journal novella in this exciting volume of the Pathfinder Adventure Path!
