The Loss: : The Originals, cartea 2

Family is power. The Original vampire family swore it to each other a thousand years ago. They pledged to remain together always and forever. But even when you're immortal, promises are hard to keep.
After a hurricane destroyed their city, Klaus, Elijah and Rebekah Mikaelson have rebuilt New Orleans to even greater glory. The year is 1766. The witches live on the fringes in the bayou. The werewolves have fled. But still, Klaus isn't satisfied. He wants more. He wants power. But when Klaus finally finds a witch who will perform a spell to give him what he desires most, she secretly uses Klaus to unleash a curse--one that brings back hundreds of her ancestors--and begins a war to reclaim New Orleans. As the siblings fight off the attack, only one thing's for certain--the result will be a bloodbath.
