The Secret Life of Sparrow Delaney by Suzanne Harper.
As the seventh daughter of a seventh daughter, Sparrow Delaney has been gifted with strong psychic abilities. But she has kept this gift a secret from everyone, especially her family! They are weird enough as it is. She doesn’t want to join the “family business” and be a psychic. She keeps telling her spiritual guides, three ghosts who have appeared to her since early childhood, that her only wish is to be normal. So when she has the opportunity to attend a new high school where nobody knows her or her family, especially her six older sisters, she jumps at the chance! She can start fresh and be totally normal. But in her first class on the first day of school, she sees a ghost. She uses all of her well practiced tricks at avoiding ghosts, but he won’t let her be! He keeps appearing to her and pleading with her to help him. But Sparrow is stubborn and she wants not part in his plan, whatever it is!
