Prologue

Elena ran toward the boundary line. She had to get there fast. She needed to. This was all her fault. She cursed herself for lying that day. For crossing the boundary and now she had done it. She had become the cause of a deadly war between two ruthless vampire clans. Her breathing became harsh once she smelled her brother's scent in the air. He was close. Life escaped through her when she smelled his fragrance too. He was there too. Finally, he would know who she was. And why? Why did she have to lie?

Not that she would ever regret it. She found the love of her life. Her soul mate. But this wasn't supposed to happen. She wasn't supposed to fall in love with the enemy. Now she had to choose. Between her family and her love. Her soul mate. Her mate. She took a sharp turn and she nearly lost balance when she saw him and her brother snarling at each other in their vampire form.

"How fucking dare you touch my sister?" snarled her half-brother, Klaus. "How dare you even think you could have her? I will fucking shred you to pieces, you're fucking dead! Dead! I tell you."

"The fuck you're talking about? I rather die in a pool of vervain before I touch any slut that is slightly related to you." Damon replied, surprised and amazed by accusations.

"Don't pretend like you don't know what I'm talking about!" Klaus growled, still in an attack stance. "You have gone too far this time. I won't spare you for this. I will tear you limb from limb. The family is off limits."

Her other siblings supporting her elder brother's statement by snarling at her lover, her mate, and her mate's family.

"Like I said," Damon began. His dark hair was sticking against his glistening forehead. "I have no idea the fuck you talking about but you step foot in my area and I will stake you myself. Treaty be damned."

He stuck his hands into his leather jacket, snarling as he turned around. He was done with talking to the arrogant, son of a bitch original vampire, he'd other worries on his mind and Klaus was interrupting them.

He paused looked back at the blond vampire and said,"And, News flash, I already have a mate."

The words didn't seem to have an effect on the other male. Damon needed to clarify himself a little more to get through the thick skull of the stubborn repulsive Original chief.

"Bitches from your side are beneath the level of Damon Salvatore," the dark-haired vampire said with a smirk. Yet, Klaus' facial expression didn't change and Damon needed to feel satisfied with having the last laugh. He stepped closer to his opponent, smiling and said, "However, if your sister still wants a good fuck, send her up. I am sure I can find someone here who would volunteer to show her what real men feel like."

Elena nearly snarled in response. He had a bad habit of taking a jibe at wrong people at the wrong time. Her brother snarled and was about to attack when Elena shouted, "Stop!"

All eyes shot to her.

Her mate's eyes widened as he saw her. His face reflected how much horrified he was to find her on enemy territory. She knew what was going through his mind. Male vampires are awfully protective of their mates and could rip off anyone in half if someone even looks at their mate the wrong way. Standing on the enemy territory meant immediate death by the rival clan. Little did her mate know that she was part of this territory too. He didn't know that she was the half-sister of Klaus Mikelson, her mate's biggest enemy.

"Elena," Daman breathed, terrified that Klaus would hurt his mate.

Klaus turned around, facing her with bloodshot eyes. "Elena! Didn't I tell you to stay at home? What are you doing here?"

"Please…don't…please," she begged with a pool of tears in her eyes.

Her eyes darted to her mate who still looked puzzled. The realization came across his face.

"You're his sister," Damon wasn't asking, he was stating.

His void emotionless face suddenly filled with emotions. Hurt, because she had hidden such big detail about her. Disgust, she was his enemy's sister. Panic, he couldn't possibly live without his mate and he knew Klaus would never let him have her. They were enemies since birth. And finally determination, he had to think something quick. He refused to give up his mate.

Elena nodded, confirming his statement.

"Yes, I was going to tell you but -" she trailed off when she heard her mate's brother growl.

"I told you," Stefen said. "Didn't I? This was all a trap. He must have sent her to finish all of us. This is a new low even for you Klaus."

"Oh!" Klaus exclaimed. "Quit it! Don't pretend like it wasn't one of YOUR schemes to trap my innocent sister and use her to get rid of me and take my territory. But too bad for you I found out."

Klaus hissed at Stefan, her mate's brother.

She avoided Damon's pain-stricken eyes.

He couldn't believe it. After years he had finally opened himself to someone. After years he had fallen for the girl in front of him. A vampire doesn't fall in love easily but when he does there is no going back. He made her his mate. They had shared blood. She was officially his now. How could she betray him like that? Was this all a game to her?

Klaus must have put her to this. It was expected from a lowlife, sick, power-hungry mixed breed like Klaus but Elena. Elena seemed so pure and innocent. How could she do this? She is his sister. Of course, she can do this. His mind answered. But what about me? I don't deserve this. I love her. His mind screamed.

"Stefan!" she begged. "There was no plan. Please let me explain. But it was too late, with a speed of lightening her mate's best friend, Enzo, crossed the boundary and held her by her neck, snarling at her as he vamped out. Elena screamed. Almost on instinct, Damon came to her defense in an instant, pushing Enzo off her. Enzo flew back to the other side of territory. A second later, Klaus was on her side too, pushing her mate off her and standing in front of her. Little did her brother know that she was his now.

"Nick! she pleaded. "Nick! Please! Don't hurt him! He is my mate. Please don't."

She tried to get in between the two very furious vampires.

Her words nearly shook her brother. He stared at her in disbelief. Elena cowered under his death stare.

"You shared blood with my sister. You made her your mate. How fucking dare you?"

Her brother snarled at Damon before he attacked him.

"Nick!" she screamed. "No!"
