Percy is at his house after leaving Camp Halfblood after the battle of the Layberinth, and has been in a stupor for a while. So, Grover decides to take him out and invite a very special someone to meet them there. This story (begining) is between the last two chapters of The Battle of the Labyrinth and time jumps to when they are older. Also (for the one person who asked) I edited one chapter so it's more clear.
