In the New York Times bestselling tie-in to the World of Warcraft game expansion: Cataclysm,

Thrall, wise shaman and the warchief of the Horde, senses a disturbing change.

Long ago, Azeroth’s destructive native elementals raged across the world until the benevolent titans imprisoned them within the Elemental Plane. Despite the titans’ intervention, many elementals have ended up back on Azeroth.

Over the ages, shamans like Thrall have communed with these spirits and, through patience and dedication, learned to soothe roaring infernos, bring rain to sun-scorched lands, and otherwise temper the elementals’ ruinous influence on the world of Azeroth.

Now Thrall has discovered that the elementals no longer heed the shaman’s call. While he seeks answers to what ails the confused elements, he also wrestles with the orcs’ precarious future as his people face dwindling supplies and growing hostility with their night elf neighbors.

The fate of Azeroth’s great races is shrouded in a fog of uncertainty, and the erratic behavior of the elemental spirits, troubling though it is, may only be the first ominous warning sign of the cataclysm to come.
