You all know Percy Jackson, the "zero to hero" guy. But this story is about Callie, his whole blood little sister. Will he have a soft spot for her, or will something else happen in the end?

It was a full moon tonight. I was riding on the motorbike I 'borrowed'.I didn't care about the speed limit so I sped down the highway as fast as I could go because I was finally free...

So I'm pretty sure you've heard of Perseus Jackson. Yeah, son of the sea god, hero of both camps, connoisseur of blue food, yadda yadda yadda. Okay, now what if I snapped my fingers in front of your face and said, bam, he had a twin sister? You'd scoff, probably. Say something about overused fanfiction ideas. And yeah, maybe I'd agree. But I'd also tell you that you'd never know until you've read, no? Buckle your seat belts, magicians and half bloods alike. It's time to meet, well... Me. [I do not own Percy Jackson and the Olympians, or the Heroes of Olympus, or The Kane Chronicles. All characters in this book other than canon characters are my own.]

No one messes with his daughter without facing the consequences. That was the first rule that is learned upon entering the sea. He would fight battles for his sons. If someone looked at his daughter wrong, thought about his daughter wrong, there would be war and the world would burn.
