I’m trying to find a book I read between 2013-2015.
The book was about a girl (all family dead I’m 90% sure from a car crash and she was the only survivor - she was also a twin) who meets a family of witches. She doesn’t know they’re witches at first etc. She finds out they’re witches and they time travelled from the early 1900s to help her gain her magic to fulfil some prophecy. She falls in love with the son and becomes best friends with the daughter. Also I think someone’s trying to kill them all but not completely certain.
I’m pretty sure she helped the family paint their house when they first moved in and she often visited her family in a cemetery.
