Can't remember the series.. help?

[Kathleen]

All I remember is that it's about a woman who finds out she is a witch but her sister is not. She gets a letter from some long lost family that live in a town only accessible if you are paranormal. Please message me if this rings a bell because I've been looking through my shelves and can't find the first book and it's driving me insane!!!
