The Dragons Return (Tales From The New Earth Book 1)

Over 3 years ago, the old Earth began to die. Technology started to break down. Electricity failed. Machines stopped working. Planes, trains and cars became useless hunks of metal. And then the dragons came. On the Night of Burning, the world's great cities were reduced to slag and rubble by dragon fire. Civilization, as we knew it. ceased to be.
But before the end came, there were the Changlings. A few humans, children and adults alike, began to mutate into...something else. Ears became pointed, fingers fused or elongated. Their old languages were lost to them and they began to babble in unknown tongues. Perhaps one in a hundred thousand Changed. Simon O'Toole was one of them.
Back then, he was a large middle-aged man. Now he's a skinny, awkward teenager, Simon has lost everything; his family, his friends, the world that he knew. But he has gained something as well. Through hints in dreams, he has learned magical runes that can summon elementals. He can cast fireballs and lightning. In short, Simon has become a wizard.
Slowly, carefully, he is learning to use this new power. It will take years to master his magic. Years that Simon may not have.
The dragons are still on the hunt. They search for survivors of the human race, and when they have been exterminated, the dragons will turn on the last remnants of humanity: the Changlings themselves.
