The Hunger of the Gods (The Bloodsworn Trilogy, Book 2)

THE DEAD GODS ARE RISING.

Lik-Rifa, the dragon god of legend, has been freed from her eternal prison. Now she plots a new age of blood and conquest.   
   
As Orka continues the hunt for her missing son, the Bloodsworn sweep south in a desperate race to save one of their own–and Varg takes the first steps on the path of vengeance.   
   
Elvar has sworn to fulfil her blood oath and rescue a prisoner from the clutches of Lik-Rifa and her dragonborn followers, but first she must persuade the Battle-Grim to follow her. Yet even the might of the Bloodsworn and Battle-Grim cannot stand alone against a dragon god.   
 
Their only hope lies within the mad writings of a chained god. A book of forbidden magic with the power to raise the wolf god Ulfrir from the dead...and bring about a battle that will shake the foundations of the earth.
