The Heroes of Olympus series but rather than Leo being alone as the seventh wheel, he meets y/n Solace, daughter of Apollo. Also this story will not have Calypso and there are eight demigods of the prophecy. All rights go to Rick Riordan (storyline etc)

She never really entertained the thought of being someone special, someone unlucky enough to be noticed by the gods. That was she didn't think these things until Leo came (quite literally) crashing down into her life.
