Every forest has its perils. But in the Wilds of Chume, the perils are manifold! Inside every plant hides a beast to protect it. The air echoes with the melodies of the Chuma—whimsical natives who live in harmony with this mad wildness. Countless weird wonders and pernicious preators fill this fey forest that has not changed since time immemorial.

From the huncell of Fevär, an incursion of humans invade this land in a campaign of expansion and conquest. Led by the master bladeweaver, Lärisa Ivoryhide, they bring firearms, civilization, and theurgic swords to cut through the ancient powers of the Wilds. The Chaos of Nature must contend with the Law of the Sword.

Through all of this, four friends trek to the distant realm of Veluora the Red to rescue one of their own. Will Foundling, a master of the woodlands, has never ranged through a wilderness so wild. Hindin Revetz, a wounded warrior, feels lost in purpose as well as place. Sir Röger Yamus finds his humanity challenged as the beast within him contends with the ferocity of this fey domain. And Polly, who is now split into two separate beings, must locate the most elusive of all things: herself. In this third volume of the series, Four Winds-One Storm must become the winds of change in a changing world.
