She also sees lines that form a grid connecting her to everything and everyone around her. As far as she knows, Ruby has no living family members. So it is a shock when Ruby finds out that she has two uncles and a grandma who want to take care of her. Finally, she will be taken care of. But having someone understand her may be more dangerous than she ever thought. An odd diamond, the mystery of her missing parents, and suspicious family members teach Ruby that to survive, she must trust her newfound friends and discover who she truly is.
