I read this series around 2008-2010. It was a multi-part fantasy series and here are the details I remember:
– girl whose mother died
– she’s in the foster system
– she accidentally set fire to her old foster parents home, killing her foster dad
– she had been in a relationship with one of her foster brothers (i don’t think it was consensual, or it just ended really bad and he stalks her)
– she gets put in a group home and it is her last chance
– she goes to a high school
– all of the girls from the group home are apart of the cheerleading team
– all of the cheerleaders, and the group home owner and groundswoman are witches/in a cult
– it’s in their blood and her mother was apart of this legacy
– the main character is also a witch she learns to use her powers
– the love interest is the groundswoman’s son who lives in a house on the same property as the group home
