Except Percy isnt a son of Neptune, Percy is a son of Poseidon. Also, if you really want to look at it, there isnt a single son of Neptune un the book as all the supposed sons of Neptune (Arion and Phineas) were both children of Poseidon in mythology. Likewise, the lost hero in The Lost Hero could be Percy or Jason as they are both lost in their own way. The Mark of Athena is the title of the book, but we dont know what this mark is or the true meaning of the prophecy. We also know from The Son of Neptune that Ella's prophecies are very inaccuate, as her prophecy about a son of Neptune drowning didnt actually happen.
