If you think all paranormal romance is the same, think again. There is a huge difference between the world building of each series and—most importantly, perhaps—how seriously the author takes their characters.
J.R. Ward’s Black Dagger Brotherhood creates a world where vampires live secretly and peacefully among the humans. They eat and drink like humans, and only share blood with their own kind. A diet of human blood would not sustain these vampires for long. The Brotherhood protects the citizens from attacks by the Lessening Society. Lessers might smell like baby powder, but there is nothing innocent about them. Lessers are created by the Omega from violent humans who give up their souls for immortality. The vampire king, Wrath, is the leader of the Brothers and after centuries of life, it appears the Brothers have more emotional scars than physical ones. Even their deity, the Scribe Virgin, is not benevolent. The Brothers know better than to ask her for favors since even the asking can get you killed, but if you ask, you must be willing to pay the pound of flesh she will require of you. For she will save your true love’s life—as long as you promise never to see her again.
