Vinculum. A word hastily scrawled on a scrap of paper left behind by his long dead parents, becomes much more than a mystery. It becomes Adriel's world. Adriel struggled with his life, traveling the world and searching for his place in it. His pale green eyes and snow-white hair instantly singled him out in a crowd, but that wasn't what made him different. As he struggled with conformity, he also waged war with himself-never able to control the raging pressure that swelled deep within him, alluring him with dark desires, tempting him to think of unspeakable things. Things no human should ever think about. When he awakens from a vicious attack, he is reborn in a world where the unspeakable is real. And they are more terrifying than the one he has fought within himself for so long. Blood-sucking creatures, terrors with razor-sharp claws, and strategists with lethal plans lurk in the shadows, living in a world of darkness. And Adriel is one of them.
