ABANDONED. YA series about voodoo in New Orleans. Read before 2006?

[[deleted user]]

Okay so it was a long long time ago, possibly over 20 years ago
and there was a series of books about voodoo in New Orleans, in which a girl named something like Ally, comes to live with her aunt and she meets twins, Isnard and... the other one... and starts to learn her aunt is a voodoo priestess and she might inherit this.
She doesn't know which twin is good and which is evil
and there was a girl who was a Loup garou (werewolf)

That's all I remember!
Does it ring any bells?

Thank you so much for all help!!!
