Graywullf - Thomas Rottinghaus - Bog

The Dark Wizard Lynch had lived several ages of men being
loyal only to himself. But when he was accidentally rescued
from certain death by the Warrior Lorn Graywullf, he found
himself in the unfamiliar position of being indebted to another. To
repay that debt, Lynch offers to help the Warriors reverse a spell
that would wreak havoc on their World. Of course, he neglected
to mention that action would serve his own interests as well. In the
process, Lynch discovers much to his chagrin that he does still have a
soul and a conscience. He also discovers that the Warriors are fighting
a battle they can't win against a common enemy, a Wizard named
Timon Backhelm. Only Lynch knows his complicated history with
Timon, and the real reason he has sworn to kill him or be killed trying.
But when Lynch realizes the extent of Timon's power, he knows the
only way to win is to initiate the creation of the Dragonspawn, a
magical, physical blend of the strengths of a Dragon and an ultimate
Warrior. The question is, will the Dragonspawn be loyal to those
who created him, or will he simply destroy them all?
