The Darkness With In Me. {Completed}

Angelica is a normal girl with normal friends. The only thing that is really not just fine is her family. Her father left when she was a newborn. Her brothers had been missing now for eight years. Angelica is going to be turning seventeen very soon. The night before her seventeenth birthday something weird starts to happen. Her birthmark on her wrist starts to puff up and turn red. It almost looks like it will pop out. The birthmark is in the shape of wings with horns on the top. Angelica starts to run to get her mom when she gets a headache so bad that she passes out. This has never happened to Angelica before. She wakes up and doesn't remember anything. She looks at her birthmark and it all comes back to her. The birthmark is now a tattoo and is getting darker by the second. What happened? Why is this happening?
