I learn what the trial is

Hayley has read about Greek mythology since she was little. She never knew it was real until one unfortunate day when Kronos kills her parents and takes her to his headquarters. He was collecting kids at the age of 7 to make them demigods. He makes them go through training and tests which lead up to the big trial when they become 13. The only boy and girl who survive this will become demigods. Will Hayley survive the big trial?
