Cave of Blood and Bone

Vampiric assassin Adina has survived her grandfather Sujani's magical schemes, only to land herself back in the deadly clutches of her estranged father-the King of Assassins With Adina kidnapped, Sujani is more determined than ever to raise his deity. If the cunning mage can't procure his granddaughter as the sacrificial vessel, he'll be forced to substitute his age-old rival, Damon-the world's only other remaining First Vampire. But First Vampires aren't so easily overpowered and if he involves Damon, Sujani may well be the one laying on the sacrificial altar. To kill one of the Firsts requires the use of the mythical Bone Shard Blade. The weapon forged from the bones of the last living dragon was lost in The Cataclysm over a millennia ago. As their quest unravels, so do Adina's feelings for Sir Elrich and his constant lies. She just wants to live her unlife as she chooses, free from the men in her family and their murderous games. However, one doesn't simply say no to the most powerful vampire in the world. With the help of her knight, Sir Elrich, and her conniving father, Adina finds herself in a race against time and the world's two most powerful vampires to locate the Bone Shard Blade. Both Damon and Sujani must be stopped, but the legendary weapon can only be used once. Adina must choose between death at Sujani's hands or enslavement at Damon's.
