Reversed Worlds (A Leo Valdez Fanfiction)

It was a normal day, or so I thought.
I was sitting in my room, doing homework, when I heard a knock on the door.
"Kate!!" My mom called from the kitchen. "Could you get the door?"
Baking, probably, I thought. Ever since my dad had died, she had spent hours just in the kitchen, making food of all sorts.
I snapped back into reality. The door.
Rushing down the stairs, I noticed my sister was speaking to someone of the phone.
"Alice!" I shouted. "Who r u talking to?"
As usual, she slammed the door of her room.
I got to the door, just as the person behind it started leaving. Panting, I opened it.
"Hello?"
"Hi!" Said the boy.
"Who are you?" I asked, still breathing heavily.
"There is no time for that!! Quickly, we much go!!" Said the boy
"No! I need to know who you are?" I pulled back from his grasp.
I recognised him. Well, in a strange way. I hadn't seen him before, but I definetely recognized him. Green eyes, Blackish hair. Extremely hot.
"My name is Percy," he reluctantly said. "Percy Jackson."
