Book excerpt: "Darkness isn't one shade, sweetheart." Three centuries ago, Molly Darling's ancestors signed a contract in blood-daemon blood-to protect themselves from harm. On the eve she turns nineteen, Molly leaves for her birthday party against her parent's wishes, sick of their warnings about her "betrothal to a demon." Except that she's very much betrothed, and he's very much a demon-one who's only agreed to the nuptials to use Molly's ancient daemon powers. Brash, arrogant, and built like a Greek god, Tensley Knight keeps showing up to save Molly from otherworldly attacks, only to insult her a moment later. As Molly learns more about the demon world, she realizes two things: that her family's safety depends on a successful marriage, while any chance of freedom she'll ever have calls for Tensley's demise. Yet sometimes Molly spots a tortured soul beyond those liquid grey eyes, and there's no denying the way her skin tingles when Tensley touches it. In Vein of Love, safety requires sacrifice, foe becomes lover, and one must decide whether to kiss...or to kill.
