Sophie Foster has a secret. She's a telepath - someone who hears the thoughts of everyone around her. It's a talent she never knew how to explain. Everything changes the day she meets Fitz, a mysterious boy who appears out of nowhere and also reads minds. She discovers there's somewhere she does belong, and that staying with her family will put her in grave danger. In the blink of an eye, Sophie is forced to leave behind everything and start a new life in a place that is vastly different from anything she has ever known. Sophie has new rules to learn and new skills to master, and not everyone is thrilled that she has come 'home'. There are secrets buried deep in Sophie's memory - secrets about who she really is and why she was hidden among humans - that other people desperately want. Would even kill for. Sophie must figure out why she is the key to her brand new world before the wrong person finds the answer first.
