The black diamond

I wrote this at school for a writing piece and people were saying how good it was and that it was like a Harry Potter piece (I don't really believe that but ok) it's about a 17 year old girl with long black hair, pale skin, skinny, green eyes, named Samantha Parker, twins named Paul and Julian Bell, who have pale skin, skinny, blonde hair, grey eyes, a teacher named Professor Young in her 50's, with a grey bun and light blue eyes and Samantha's crazy aunt calleed Scarlett White that has scarlet red hair, and black eyes and a gothic look.
Samantha is a badass boss type, Julian is Draco Malfoy 2.0 and Paul is kind, and nice Professor Young is strict but fair and over protective, and I'm sorry for spelling mistakes I'm on my phone and for some reason it's harder to type than before
