This is Book 6 in the; Moiraio series Fem!OC x Leo Valdez. If you have not read; -Moiraio -Trickery -Burden -Twisted -Cruel DO NOT READ THIS YET: It is very crucial for my characters storyline that you understand it. You cannot read the Heroes of Olympus series until you've read the Percy Jackson series. She is Percy's Twin sister so it will be different. PLEASE trust me on this one. This would be in the normal series, The Lost Hero. Kiera Jackson is sent on an extraction team and meets someone unexpected. As they bond throughout the school year, she can sense something is off with the school. On the field trip to the Grand Canyon, something goes horribly wrong-per usual for a Jackson kid. Kiera will have to work hard on a quest to save an unworthy goddess, and after, deal with an annoying crush.
