World of Warcraft: Vol'jin: Shadows of the Horde: Mists of Pandaria, Book 2

Traces the aftermath of Cataclysm-induced disasters through Azeroth, where an all-out war erupts between the Horde and Alliance and threatens to consume both factions.
War is coming. Vol'jin, courageous leader of the Darkspear tribe: his strength and cunning are unmatched even among the Horde's most exalted champions. Now on the legendary continent of Pandaria, the troll chieftain faces his greatest trial yet, one that may redefine his purpose in the World of Warcraft. Warchief Garrosh's assassins strike at Vol'jin, leaving him at death's door. But fate smiles on the wounded Darkspear leader when renowned brewmaster Chen Stormstout transports him to the safety of an isolated mountain monastery. There, Vol'jin wrestles with old hatreds smoldering between the Alliance and the Horde as he struggles to recover alongside a mysterious human soldier. Yet this is only the beginning of Vol'jin's worries. Soon, he becomes embroiled in an invasion of Pandaria launched by the Zandalari, revered trolls driven by dreams of conquest and power. This ancient tribe offers Vol'jin a chance to seize the glory that is the birthright of all trolls . . . an offer made even more tempting after Garrosh's brazen treachery. Amid these troubling events, Vol'jin is rocked by intense visions depicting his race's grand history. As he questions where his loyalties lie, he knows he must make a choice about his own destiny that could save his people or damn them to languish under Garrosh's heel in the Shadows of the Horde.
