You don't know how this happened.
First you were hanging out with your bestfriend, Percy Jackson, on his beach house with his mother, Sally Jackson. Two seconds later, you were both running under the rain, escaping from a Centaurus. And Percy and you were actually somehow demigods, and Greek Mythology existed in real life...
Sally was no-where to be seen anymore, but there was no time to grieve. You three had to escape.
The rain was getting heavier and heavier, but that didn't matter. Grover was guiding Percy and you through the forest, Percy's hand holding yours. You two running for your lives. A mist surrounding you.
"Shit shit..." Percy muttered, he held your hand tighter. He was frantically looking for Sally, the pen on his pocket was moving on its on, vibrating.
