Heroes Of The Olympus: The Lost Hero begins with Jason returning to consciousness on a school bus next to Piper, his girlfriend, and Leo, his best friend. Jason is suffering from memory loss and can’t recollect many things. As the trip proceeds, the trio and the coach are attacked by Dylan, a classmate who turns into a storm spirit. Jason, to everyone’s surprise, turns one of his coins into a sword and fights with it. The fight ends with Coach Hedge, actually a satyr, being taken captive by a spirit and a flying chariot arriving to pick the trio up. However, a classmate Annabeth is upset when she finds that her boyfriend, whom she had come looking for as directed by Goddess Hera, is not amongst them.
