Leo goes to Athens, Greece without the burden of a prophecy to get his mind away from his loneliness and to make peace with the trauma from the last war. Along the way, a series of events and a fascination with dragons lead him to an unexpected discovery: a place that feels like home where he fights monsters, saves dragons, and encounters a certain trio and a pair of twins.

Crashing face first into a lake was not how Leo had planned to end his day. First his best friend not only forgets who he is, but turns out they actually hadn't met before that day; then he had to hold onto a ledge for dear life and a satyr had to save him while Jason kicked ass; then he almost gets kidnapped by some crazy wind guy and overall it was a terrible and amazing day.
