PJO fanfic: Destiny Masdellan and Friends (using my own characters)

Destiny used to live a somewhat normal life, going to (multiple) normal high schools with teenagers her age. Until she woke up to a one eyed creature outside her window and was pulled through a row of shrubs on her way to school on a very peaceful morning. ...But...........
Can Destiny and her new friends save all the crops in America from dying completely and be the countries biggest hero's when they arrive back in Camp Half-Blood? Or will they fail, and be captured by the enemy?  This might change, since I just started writing again I don't know if I want to keep this idea/plot.
