Shadows Beneath the Waves

It was a dark and stormy night... No that's not it.
I, Avery Collete, am the only one who can save them.
On that normal day of the parentless, twenty year old life I was living I expected nothing more than normality. But then he showed up.
He seemed to be interested in me, eager to protect me. He said he knew something about me that I didn't know myself. Something about my identity. He tells me of this war between these kingdoms because of some violated treaty. A ruler wants me dead or at least imprisoned. I hesitated trusting him until an event kind of proved otherwise. He risked his life to protect mine. On top of that, there's a prophecy that says in order to defeat the ruler I have to do something that is unheard of and hard even for me. I don't want to come in contact with those from my past. My head fills up with questions and worry. Why does this ruler want me dead? Will I survive? Will my friends survive? Why do I have to carry this burden on my shoulders?
How could one day change a life forever?
