Book excerpt: An elegant vampire goes to hell and back for the demon he loves in this paranormal romance by the New York Times bestselling author of When Darkness Comes. Lady Shay is the last of her kind. Half human, half Shalott demon, her blood has healing and aphrodisiac powers that vampires consider more precious than gold. Though Shalotts are renowned assassins, a curse held over Shay lands her on an auction block, where she catches the eye of a Vampire named Viper. The beguiling chief of a deadly vampire clan, Viper can't explain his longing to possess the beautiful Shalott who once saved his life. He desires both her blood and body, but even when she is his, he wants above all for her to surrender willingly. But a hidden evil continues to stalk Shay—one that endangers the very existence of Viper's kind. But the love he feels for her is enough to make him go to hell and back if it means spending an eternity with her in his arms.
