All rights go to Rick Riordan, for he is the one who began the Percy Jackson and the Olympians series, as well as the Heroes of Olympus series. Jenna is merely creating a fan fiction with characters in the original two series. The Percy Jackson and the Olympians series, the Heroes of Olympus series, and other Percy Jackson related books by Rick Riordan are from the writing of Rick Riordan, and Jenna's book is just a fan fiction. She owns no one unless an OC is made, then Jenna owns that person(s).
Sincerely,
The Fates
