LAST CHAPTER 

Gaea's POV

I roared in rage as one of my servants told me what had happened to Percy Jackson, fortunately after he escaped he left a hair, maybe not much but the blood had dried up, I picked up the hair and recited the spell the hair glowed and a new Percy, an evil Percy appeared. I laughed wickedly "oh Percy, Percy, Percy you won't be able to kill yourself" I said and laughed evilly

Percy's POV

After the questions from all the campers and my friends I was finally at peace, until the conch horn of a battle went off, I run up the hill and saw gaea with..... me? I stood there shocked as well as the rest of camp "I give myself, I will kill myself if... you Percy Jackson can kill your evil copy" she says with a smirk. I look around at my friends, I can't put them in danger, never "I'll do it" I say and everyone including my copy and Gaea looked shocked, I desheathed my sword and attack and he blocks with an identical sword, I look into it's eyes and we have a silent agreement, I stab at his stomach but he blocks, he tries to slice my head off but I block we go on again and again and again until I jumped up and sliced down and it hits him but it does not kill. He strikes up and makes a cut on my srm but it doesn't kill me either. We strike, block, return, slice, kick, stab but neith seems to land a hit so I resort to powers, I blow a ball of darkness at him but he makes a wall of Chaos. We never seem to get the upper hane and we were both getting frustrated buth neither stops fighting or gives up. Everyone was watching us "Gaea, If I kill him you kill yourself? If it's true swear on the river Styx that if I beat him you die!" I yell as the Olympians appear "I Gaea swear on the river Styx that if you beat your duplicate that  I will take my own life" she says and I look at my copy and nod, we both turn to her and throw our swords, mine hits her heart and his does too, the swords make her fade into the void never to be seen again. I take a deep breath and absorb my copy "the war is over! Everyone may rest now, until next time" I tell everyone and grab Bianca by the waist and kiss her

THE END

I know this is short but I love the way it turned out, nice plot twist so don't blame me!
