Isabelle is practically invisible in sixth grade, where she is friendless, lonely, and the days are dull. All that changes when she opens a door and falls into a different world, one where villager children are convinced a witch is out to get then. Isabelle meets her healer grandmother in this alternate universe, gets to know her and realizes that she is the one who is the purported witch. It is up to Isabelle to correct the misunderstanding and set the record straight.
