Look, I didnt want to be a half-blood.
If you're reading this because you think you might be one, my advice is: close this book right now. Believe whatever lie your mom and dad told you about your birth, and try to lead a normal life.
Being a half-blood is dangerous. It's scary. Most of the time, it gets you killed in painful nasty ways.
If you're a normal kid, reading this because you think it's fiction, great. Read on. I envy you for being able to believe none of this ever happened.
But if you recognize yourself in these pages-if you feel something stirring inside- stop reading immediately. You might be one of us. And once you know that, it's only a matter of time before THEY sense it too, and they'll come for you.
Don't say I didn't warn you.
