Annabeth- 1992(13 during 2005, 14 during 2007 which is when the first book takes place and 10 when she meets thalia and Luke during 2003) Luke will be the same age as Thalia and valin when they meet.

By the time of the first book, they'll all be 18

Making all three 12 during that time

But I've changed it, so the time they leave and make it to camp is 2003, making them 15, and the events of the first book of Pjo will take place during 2006, making them all 18, percy and annabeth will be slightly aged up to 14
