The Fall

Annabeth’s first thought waking up alone in Percy's bunk was “where did that boy go?” I noticed the door to the cabin was still locked from the inside. I peeked under the bunk to make sure he wasn’t playing some cruel joke on me. I couldn't find him in the mess hall or on deck, and I was really getting worried.
I knocked on Piper's door and Jason answered. “Annabeth?”
"Have you guys seen Percy?"
Piper peeked out from behind Jason. Annabeth couldn’t help but notice that Piper obviously just woke up, but she still looked beautiful. I silently cursed the children of Aphrodite for effortlessly looking beautiful. Piper stretched her arms and yawned, "Not since last night. What's wrong?"
"I can't find him."
"Hold on, let me get dressed and help you look."
She pushed Jason out with an indignant look on his face and shut her door. In less than 3 minutes she emerged and the girls went down the infirmary, engine room, and stables.
I was starting to get apprehensive when they went door to door and no one had seen him. I even got Leo to ask Festus if he had seen Percy come above deck. We heard some whirls and clicks come over the intercom, the machine language that Festus spoke and only Leo understood.
"Sorry Annabeth, he says you the first person to go on deck since I set the autopilot last night. No one has opened the Pegasus stables doors either.”
The blood drained from my face and I collapsed after saying, "No, please not again. After all we've done.. not.. aga..”

I had only one dream while she was unconscious. The same nightmare I had almost every night since Percy and I had returned from Tartarus.
I was standing in Arachne’s cavern, in Percy’s embrace. My friends staring at the 40 foot statue of my mother. There was a tug on my foot, realizing too late a strand of spider silk was wrapped around my ankle. I face planted hard, Percy not understanding what was going on until he saw me fall over the edge. As I looked up, Percy’s face appeared over the edge, but it got smaller and smaller as I fell and fell and fell into the darkness.
I would fall for what seemed like days until she fell into a river. The River Lithe. Somehow I survived the fall, and I could feel my memories fading away. For a single second, I would forget who Percy was.
At that point, I would normally wake up in a cold sweat, not knowing where I was for a moment. The only thing that would calm me down was Percy's warm embrace, the way he smelled like the sea, and his green eyes pleading with her that he would never let me fall alone. I often wondered what would happen when they got back to camp. Members of the opposite sex were not allowed in each others cabins alone unless they were Godly related. Chiron would not make an exception for nightmares, even if he practically raised me since she was 7. Percy and I had promised each other that they would never get separated ever again and I was sure that I would not let us be.
When the dream did not end, I felt in my gut something was wrong, but I did not know what because of my little dunk in the Lithe. I wandered the plains of Tartarus alone until out of nowhere four long, thin, barbed legs snatched me up. I didn’t know what this creature was, but I was frightened down to my core, some primal fear. It pulled my face up to its mandibles and whispered something.
it’s breath was not what I expected. It smelt of spearmint toothpaste and the sea. It said “I’m here.”

Notes

Honestly, I have no end point planned, I'm just making it up sentence to sentence. Let me know if ya'll want more. I have about half a 2nd Annabeth chapter written up atm.
