Ali and her family have moved to a different town at least once a year, ever since Ali can remember. She’s been to six different schools, lived in dozens of apartments, and has never felt truly at home anywhere. But Ali’s parents say Saint John will be different. They’ve moved in with Ali’s great-grandmother—a spunky 99-year-old with a quirky old house that has room for all of them. Ali wants to believe this will be their last move, but everything seems too perfect to be true. As it turns out, things are different this time, but not in the way Ali hoped. She's finally inherited her father’s magical ability. When she makes eye contact with a classmate or relative (or any living thing, for that matter), she starts to mimic their behavior, mannerisms, and appearance! Ali is a copycat. Literally. And being the new kid at school is hard enough without worrying about turning into your teacher. Luckily, Ali's new friends (who are well-schooled in magical abilities due to their love of Harry Potter) are eager to help her use her newfound power.
