The Sword of Heracles

Nicolette Thompson was an ordinary high-school student sitting in algebra when she and another boy were called to the office. Unbeknownst to her, her life was about to change.

Jason Dean loved the Greek myths, the stories of Percy Jackson and his adventures. He'd just finished his math test when he along with another student were called to the office. He's gonna need all the knowledge in his possession if he wants to stop himself from being killed, and save his new friend from her own ignorance.
This takes place in Nevada, approximately a couple months after the Titan War

The Sword of Heracles is our own spin on the Percy Jackson series.
Fair warning, I wouldn't recommend reading unless you're okay with darker themes, sexual innuendos, and extreme language.
