His Eighteenth Birthday

A short story about Percy turning eighteen.

Percy wakes up with a tingling feeling in his legs. He doesn't know where it's coming from, or what it means. When he and his family visit the beach, he finds out what it means the be a son of the sea.
Later his father stops by to wish him a happy birthday. Percy has a lot of questions, and his father has the answers.

NOTES:
I do not own any of the characters, I'm not Rick Riordan.
Post giant war.
English is not my first language, so I'm sorry if I use wrong grammar, spelling or words.
When I wrote this, I didn't think about Percy having a babysister, so she won't be making a appearance.
I hope you enjoy this little story!
