Prophet of the Dead

With Rashemen facing imminent destruction, Aoth and his companions go head to head with an army of undead, in this anticipated climax to the Brotherhood of the Griffon saga
 
The heroes of the Brotherhood have been scattered by the rising tide of undead, unable to use their combined strength to avert the coming disaster in Rashemen. Aoth—separated from his black griffon, Jet—finds himself deep in the interior of Thay, where the price on his head pays dead or alive.
 
Mercenary Jhesrhi Coldcreek and priestess Cera Euthros are lost in the deathways even as Lod, leader of the Eminence of Araunt, shepherds his undead minions through the same eldritch channels en route to corrupt the magical Urlingwood.
 
Routed by the dastardly sellsword Mario Bez, Brotherhood ally Vandar Cherlinka is the lone survivor of his berserker lodge. Together with the Shou shadow sorcerer Dai Shan, he must find a way to nurse the injured Jet back to health amid the malevolence of the wintry north.
 
All the while, agents of the Eminence of Araunt have infiltrated the masked witches, steering them toward doom from within. It will take several strokes of luck and help from unlikely sources to reunite our heroes in this fight to save Rashemen from the necrotic corruption of Lod and his army of undead.
