Daniela Girard has survived the fall of humankind by remaining useful to its new vampire masters, but usefulness cannot purchase the medicine her ten-year-old sister, Ava, now needs.
With their father gone and their stepmother lost to blood addiction, Dani turns to the blood auctions, offering the only thing she still has: herself.
Rescue comes from the last person she wanted to owe: cold Crown Prince Alexander Visconti, heir to the vampire throne.
Each time he feeds from her throat, Dani feels a dark, inexplicable pull toward a man she should avoid, and every kiss she ought to refuse buys Ava a few more days.
Neither expected the bond that takes root between them, yet it only grows stronger with every taste of her blood—and far more dangerous if anyone finds out.
