Fics like The Undertow and Its Threshold

Percy Jackson never expected much from a second-grade field trip—certainly not to be singled out by a too-smiling guide, shoved into a shark tank, or to have a complete stranger with a golden mask save him from Gabe. Between escaping danger, dodging problems at home, and stumbling into a world that seems to know him better than he knows himself, Percy is starting to realize there’s more to his story than he ever imagined.
