Ok so I know this is supposed to be a tag book, but I decided to make it also a Headcannon and one shot since I had an idea and I had to write it. Demeter_Kid helped me with it.

Annabeth always loved listening to mortals songs, even after she married Percy and they moved to new Rome . She thought they were good, and some made her cry. Like Stand By Me by Rachel Patten, or Battle scars by Paradise fears, or See You Again by Charlie Puth and Wiz Kalifa. They just made her remember her hardships as a demigod. But one song in particular made her feel something different, 7 years by Lucas Gram.

The first chorus was about him being 7 years old and being poor. 7 years old is when she ran away from home.

11 is about him making do with what he had and finding his place in the world. 11 is when Percy came to camp and she went on her first quest.

Twenty is the best years of his life. He is able to sing and even though he had hardships, he is having the time of his life. She thought that matched up with her years with Percy before the Titan war. Even though she was fighting monsters and Luke had betrayed her, she had Percy.

The next verse was about how
he had finished what he had always wanted to do and was almost done with his stardom. That as how she felt after the Giant war and when they moved to new Rome.
But there was one line, that every time she listened to it made her cry;

Most of my boys are with me, (that was the 7 of the prophecy) some are still out seeking glory, (Thalia) and some I had to leave behind, my brother I'm so sorry.

Luke. She had even called him her brother before. He had sacrificed himself and died. And now he was gone.
