Rains of Blood, Skies of Pain, Book One: The Dragon

In a world gone mad, a terrible, demonic creature with the ability to turn our most horrifying nightmares and depraved, sickening fantasies into living, breathing monstrosities—twisting the very fabric of reality itself, like a lump of clay, into one great big giant horror show projected onto the screaming screen of our waking lives, giving these nightmare apparitions flesh and blood and the desire to kill—is systematically carving its way through the population of the U.S. It is up to the Dragon, a warrior with a strange and mysterious connection to the demon, to lead a ragtag army of unlikely soldiers into battle against the beast. But will this warrior's greatest strength--the weird kinship he seems to share with his enemy--lead them to ultimate salvation, or imminent destruction? Can Dragon survive the truth about who, and what, he is?

"Dragon was the toughest son of a bitch Mari Antonia Spangetti—Mari Antoinette Spaghetti to her friends, and you’d better be one of her friends calling her that or else Little Miss Spaghetti would split your lip and send ya’ running home to mommy—had ever known. Harder than steel, this man. Only he wasn’t really a man, exactly. Not a normal one, anyway. No, her teacher, her master and Warrior General, and her friend, was something—else. Something quite different. He was fearless, and that fearlessness had rubbed off on her. She was his surrogate daughter, even though neither one of them had quite grasped that concept or would have known what to say to such a charge. But there it was, unspoken and perfect. He would do anything for her, and she would do the same for him, if needs be. But that was the beauty of their relationship: Each knew the other’s needs, but there was no fighting for common ground because both of their needs were the same. Kill the enemy, and kill them quickly. Squash them like little bugs, before they squash you. And take your revenge on them, for what they have done to you. For what they—IT—have taken from you.
Yes, she would do anything for Dragon. Absolutely anything. Except this.
Anything except for this."

“I’m going to eat you, Dragon,” the demon said. “Just like you ate of me. I’m going to rip out your insides and feast upon them. Not because I'm angry with you. You were just doing what you were born to do. And so am I. I want to find that spark in you, that illusive spark that makes you, you—and made you what you have become. And, once I've eaten you . . . and once I've found that spark . . . you will be reborn, inside of me, and we will be one.”
