The Dragons of Bone and Dust (Tales from the New Earth Book 7)

It's been almost ten years since the Earth was forever changed by the return of the dragons. Humanity was virtually wiped out on the Night of Burning as city after city crumbled beneath the magical fire of the huge wyrms. The few survivors, physically Changed by the magic that was pouring into the world, found themselves hunted by monstrous drakes guided by the old dark gods. Mankind was on the verge of extinction.
But out of that disaster arose a new kind of human; a select few who learned to focus and use the magic around them. Mages, witches, paladins; these Changlings fought back against the Darkness to save what was left of their people. And the greatest of these was Simon O'Toole.
Once a middle-aged I.T. worker, Simon was Changed by the gods of Justice into a powerful young wizard. He used his new abilities to strike back at the dragons, saving as many people as he could.
But now, on the verge of defeating the few remaining agents of Darkness that roam the New Earth, a far greater threat has arisen; an undead horde that is sweeping across the land, hunting down the last of the Changlings.
Can Simon and his allies stand one last time against the forces of evil? Or has humanity finally reached the end of its bitter struggle?
