Planter's Moon. The Moons of Epigaea, #4

The end has come! The world of Epigaea, once ravaged by the Great Storm that nearly destroyed her, now faces one even stronger. A festering, pustulent evil from a past remembered only by the Elves has returned with an appetite only sharpened by the centuries of its delay. Goblins, hobgoblins, ogres, trolls and worse swarm from the Wild Lands into the Seven Kingdoms of Man bringing death and destruction in their wake.
Even more chilling, the spirits of the dead have returned to the world of the living. All is not lost, though. Tigerthorn the Sly, Dirk d'Argent and their friends have the means to avert annihilation. They must needs only discover where it will happen, where it will begin and how to prevent it. Thus begins the desperate quest that scatters them throughout the Seven Kingdoms and beyond. As they walk its paths they must confront old friends and enemies both in their search for knowledge. Will such knowledge be enough? Epigaea's magic has diminished to nothing against that she granted before the Great Storm and it will not be enough to save her now.
The key to her future lies in her past and saving life requires death. Can the unlikely band of heroes make the necessary sacrifice?
