Starting the Heroes of Olympus series

[Alexis]

"Jason wasn't scared of heights. he was scared of being smashed against the canyon floor five hundred feet below. He figured he hadn't accomplished anything except for dying along with piper, but he tucked in his arms and plummeted headfirst." This is during the first fight in the book with a Ventus. I think it would take a lot of courage to jump head first off a bridge towards the bottom of the grand canyon.
