The plot could involve Percy arriving early to camp and immediately noticing that something is wrong because Annabeth is missing.

He forms a small group of trusted friends from the camp and they set out to track down the enemy responsible, all while Percy is struggling with his grief and guilt for not being there to protect her.
At first, Percy would be in a state of shock. His development would start with this numbness, but as time passes, it would turn into a seething anger. He would start to see the world in a more cynical way. He might become more solitary, spending long hours training or researching how to get revenge. His loyalty to the camp could be tested as he blames the camp's security or lack thereof for Annabeth's death. However, in the end, he could also grow to be more empathetic towards others who have lost loved ones, as he has now experienced that pain deeply.

Perhaps they were caught in a compromising position while having a private moment. This could lead to all sorts of awkwardness among their friends at the camp. They might have to face some teasing or even get in a bit of trouble with the camp counselors for not following the rules.
