When Katara discovered a secret hidden from the world, the fate of Zuko Sozin, she was unknown to the fact that would be her same fate. The day she found that picture would change her life forever. And some people don't take this change lightly and will do anything in their power to stop her.

Let's find out!

Chapter 1: New Beginnings

The school year was slowly coming to a close. Both Sokka and Zuko would be graduating in a few weeks and leaving high school. Sokka was planning on attending a community college nearby so he could still be near Suki and live at home. Zuko had become part of her family. Her father thought him to be the perfect gentleman, after he got over the "If you hurt my daughter, I'll break your neck phase". Same went for Sokka. Although Zuko and Sokka had an interesting start to say the least, they had become like brothers.

But summer meant new beginnings for everyone at Kyoshi High. Summer was the last time Katara would ever be human. And she wasn't even sure if she'd be able to return next semester for her senior year but she didn't have a choice. If Ozai saw that she was human by next fall, there would be consequences.

For all she knew, this could be the last times she had with her friends and family. Zuko had explained to her what being changed meant. Some vampires can't live a normal human life because of their thirst. Some can but there was no way to know until she was changed.

So Katara tried to make the most of this last school year, spending this time with her friends and family.

It was hard for her to imagine at the beginning of this year who she was. She was someone who sought revenge on the people who made her life miserable as a child. She was in a relationship that was unhealthy. Then Zuko came into her life and everything changed. She fell in love. She learned the new meaning of what love actually means. It's hard work and sacrifice and friendship. It's not selfish. It's not greedy. It is ultimately finding who your souls connect. And that is exactly what Katara found. And now, for the past 3 months, she has been content and happy about what her future held.

"What are you thinking about?" Zuko asked her, pulling her from her thoughts. Katara looked up at him. They were sat at their meadow, it had become the spot they would go to in order to get away from everything and everyone. The end of the year was also bringing stress to both of them. It was nice to have a place to escape from all of that. She shook her head, "Just daydreaming…" he smiled and placed a kiss on her forehead.

Zuko sighed, looking at the watch on his arm, "We should get going. Your father will be looking for us" Katara frowned a little, not wanting to leave their little getaway but knew they had to. They couldn't hide away forever.

When they got back to Katara's home, they weren't surprised to find their group of friends over as well. "Ah well where have you two lovebirds been off to?" Toph asked, teasing them. "Probably making googly eyes at each other all afternoon" Sokka said, laughing. "Yeah shut up" Katara shot back, "You and Suki aren't the epitome of subtlety either", everyone was laughing and joking at their sibling back and forth, except for Aang.

Everyone had gotten used to Zuko and Katara still being together, except for Aang. It was slowly growing on Zuko's nerves. Katara had made her decision, why couldn't he see that! He had already had a problem with the boy from the past, but Zuko wasn't that person anymore. If he was, things would be a lot different. He wouldn't have found his mate. He wouldn't be where he was. He wasn't that person. Why couldn't Aang see that?

Katara noticed how Zuko became slightly down cast soon after they had arrived at her home. She tried to subtlety ask him what was wrong, giving him a look of worry. But he simply shook his head not wanting to discuss in front of everyone. She reminded herself to ask him about it later.

After a few moments, Zuko walked out back without saying a word, most of the group too enthralled in their conversation to notice. But Katara noticed the way his hand lefts hers and his eyes met the floor as he strode from the room. She also noticed how Aang followed him after a moment.

Zuko looked towards the sky. He didn't know what to do about the monk. Their history was far too deep to make amends. And he clearly disapproved of him and Katara. But he was Katara's friend, how could he-

"We need to talk"

Zuko turned around to see the boy who haunted his thoughts. "Okay, lets talk."

Aang walked towards him, "You are not going to change her" he said sternly. But Zuko shook his head, "That's not your decision, its hers" and ultimately it was true. Zuko didn't force her into this. She decided that she wanted to become one of his kind. Aang scoffed, "Just three months ago, it wasn't what she wanted. She cares about you enough to not let you die, not become one of you"

Zuko looked at the boy questioningly, "How do you know that?" he asked him. Zuko and Katara had not shared it with anyone. "I have my ways. Fact of the matter is, you aren't going to change her. You know what will happen if you do" Aang crossed his arms, trying to stand tall next to the fire bender, even though Zuko towered over him.

Zuko stood over him, "It's just as dangerous if she doesn't. My father will kill her and I can't lose her"

"But you may lose her anyway! We both know the change is dangerous! And what would happen after could kill both of you! I want to save her just as much as you do but changing her isn't the way to do it. Because we won't hold back." Aang glared at the man as he shouted at him, while trying not to alert those in the house.

But Zuko did not back down, "And we will be ready." He told him.

The younger boy stormed back inside, trying to keep composed when he entered the room with his friends. "Is Zuko okay?" Katara asked as soon as he stepped foot in the room. Aang shook his head, "He's fine. I'm gonna head home. Not feeling well. Later guys" with that he left the room, not waiting to hear his friends response.

Zuko took a deep breath after the boy left. Things might be a lot more complicated then he thought.
