The first book of a vampire trilogy. They lived here from the very beginning—wild and bloodthirsty. They killed each other for food. Then people appeared. People became their food. They were the gods of people. But when people became too many, they had to hide and go into hiding, search for slaves—so that people would continue to supply them with food, and they, in return, granted immortality to their slaves.
But immortality gets tiresome and drives them mad. Immortality brings loneliness. Besides, sooner or later the servants begin to change—to resemble their masters. This gives them new abilities, but takes away the last remnants of humanity. They are left with only two options: either die, climbing onto rooftops to meet the dawn, or gather into groups and feed on people the way their masters do.
There is also a third path—finding a replacement. But it’s very difficult to explain to an ordinary person that you want to exchange immortality and invulnerability for a couple of years of life—like a regular person.
