Rick Riordan owns the Kane Chronicles. I'm just writing this for fun.
Sadie
I opened the door and quietly crept inside. I didn't have to worry about anyone catching me coming in so late since Carter and I were home alone for the weekend, and Carter is the only sixteen year old in the world that is actually asleep at eleven o'clock in the evening.
I also didn't have to worry about anyone seeing my puffy eyes or red nose. Sadie Kane, magician of the House of Life didn't cry, but Sadie, Carter Kane's little sister and girlfriend of the god Anubis did. Not bothering to walk upstairs to my room I sat down in the big chair in the living room and tried to go to sleep. Unfortunately all I could do was think about Anubis.
"Sadie, I love you so much. You know that. Spending time with gods is the last thing you should be doing under the circumstances, so dating one should go without saying. I could never live with myself if something happened to you, you have to understand that. I love you but if that means not being together until things get better, then that's the way it needs to be. Please forgive me."
Before I had time to protest, he kissed me, warm and sweet. As he pulled away he whispered in my ear, "I'll come back for you Sadie Kane." And then he was gone.
I know he loves me, and nothing will change that, but he's one more person gone from my life. The hollow feeling left from mum and dad became a gaping hole when he left. 'It's for the better', I reminded myself, but feeling alone just makes things worse. Silent tears streamed down my face. Curling up in the chair I tried not to sob. It started to rain outside, the raindrops cascading down the window pane, as if mocking my tears.
Carter
It was getting late and Sadie still wasn't home. It's gotten to a point where I know that I don't have to worry about her, especially when she's with Anubis, but I still can't help but feel anxious when she doesn't show up on time.
A while later I heard the door creak open and footsteps retreat into the living room. I walked downstairs to see if it was Sadie, carful to make no noise. As I turned the corner I saw Sadie. She was sitting in the big red velvet chair that Uncle Amos usually sits in. As I went closer I could see that her eyes were puffy and her nose was red as if she had been crying.
I slipped into the shadows and silently went closer. I stood in the dark for a while longer, watching her cry. At first I felt angry that someone had made my sister cry and then it dawned on me why she was crying. Anubis. Staying around the gods was especially dangerous right now, that's why Bast left for a while. Why hadn't I thought of Sadie and Anubis?
They had been together since a while after she turned thirteen and had been going steady for just over a year. My anger turned into sadness. I know how much Anubis meant to Sadie, and I know how much it hurts to lose someone you love.
Sadie had been there for me when we realized Zia was missing. Sweet, funny Sadie was as loyal as a sibling could be, despite being at each other's necks all the time. Watching my sister cry hurt me as much as my sadness over Zia hurt her, so I walked out of the shadows and walked towards Sadie.
Sadie
Out of nowhere came Carter. He squeezed into the chair with me and wrapped his arms around me. At first I was beyond embarrassed that he had caught me crying. As he rocked me back and forth and stroked my hair the embarrassment melted into relief that I didn't have to be alone.
We sat there for a long time. I had a feeling he knew what my tears were about, but I didn't bother to ask. He didn't ask either, just letting me think. Soon, we drifted off to sleep.
When we woke up sun was streaming through the window. I had never felt so thankful to have Carter for a brother. As Carter got up to go make breakfast he pulled me into a hug.
"I love you Sadie. I'll always be there for you."
