FLASHBACK
I was just walking to the beach to relax when I see two figures making out and everything. So I go closer to see who it is and I see that it's Annabeth and my new jerk brother Matt. Matt had come 2 weeks ago and he already stole everything from me some of my friends but I still had Annabeth, Nico, Thalia, Hazel, Frank, Will,and Piper. Jason became best friends with my jerk brother and left Piper to be a player. Leo had died in the giant war and so did many other of my friends. Now Annabeth left me two.
So I walk up to Annabeth and yell at her "WHAT ARE YOU DOING KISSING THAT B*TCH?" Annabeth looks at me and said "I love Matt and I all ready am his girlfriend because we all ready made out." And I glare at her and I slap her so hard I know that I am going to leave a mark and I run away. I go to my cabin and grab my sword and stuff clothes into my backpack and I hide everything that was my so that no one looks at it. When I'm done I see that Poseidon and Athena are giving Matt and Annabeth their blessings. I run all the way to Thalia's tree and I leave a note on it so that my remaining friends don't worry about me. And with that I take off .
Two weeks have passed and I've been hiding in the woods and fighting off monsters until one night Chaos comes to visit me offering me to join the league of assassins so that I could protect people and I agree so he teleport me to his castle where I meet all of my dead friends who were all ready in the league including Luke, Zoe, Bianca, Castor, Charle, Silena, Ethan, Michael, Leo, and Lee were all ready in the League and so I became the leader because of my skills and because everyone vote on me and Luke was second in command with Zoe next to him. But later I noticed that someone else trained with us it was the Phoenix Alex daughter of Chaos. We both hung out a lot and soon I fell in love with her. And when I ask Alex out I had helped from my friends who made diner and made everything nice and beautiful. And when she said yes everyone cheered and Chaos even approved of my relationship with Alex. Now Alex has become the most important thing in my life.
