“Forever. For always. For eternity.” The ties that bind two hearts are powerful. For Ascher Rousseau and Shauna McCutchin, it’s more than just a blood bond. Their union is that of vampire legend. Their love is a predestined prophecy foretold centuries ago. It’s a week before Ascher and Shauna's sealing and the couple is making final preparations for their eternity, but Ascher's ex has other plans. Ursula is hell-bent on revenge—revenge fueled by lover's scorn and her father's death—and she begins breeding a fresh army of newborn darklings to do her bidding. When Ursula finds a new weapon—an ally with the capability to dismantle the Rousseau clan— Ascher and Shauna's bond is tested and they must stand together against Ursula or lose each other for eternity.
