The main character, Percy Jackson, has a few significant girlfriends throughout the series:
* Annabeth Chase: This is Percy's main love interest. They are both demigods and have a strong bond throughout the books.
* Rachel Elizabeth Dare: While not romantically involved, Rachel is a very important friend to Percy. She is a mortal with strong magical abilities, and she plays a crucial role in the series.
It's important to note that the series is primarily focused on Percy's adventures and the fight against evil, not on his romantic relationships.
