Are there any good books that are about witches?

I am looking for a book that is somewhat similar to the tv series Hex or Charmed.
Or the movies 5ive Girls and the craft.

I would like it to be a little dark and I want magic, and I want the main people in the book to be girls from the ages of about 17 to 25.

Someone please help me?

 

i started reading a book called Witch Child by Celia Rees. i didnt finish it though so not sure if its what your after but might be worth a look .

 

Harry Potter!!! well i guess this doesnt fit the criteria exactly but they're still amazing books

 

I have read all of the Harry Potter books already. I am looking for a group of chick friends that are witches or have powers. I don't want the book to be about superheros just witches. And I would like it to be set at an all girls boarding school.

 

I like the Night World series
