Trixie the Halloween Fairy is an installment in the Rainbow Magic series, focused on the holiday of Halloween. Trixie is responsible for the friendly magic of Halloween—the fun of dressing up, the excitement of trick-or-treating, and the spooky but safe atmosphere. When her magical item is stolen by Jack Frost, Halloween goes horribly wrong: costumes become truly scary, pranks turn nasty, and the atmosphere becomes genuinely frightening. Rachel Walker and Kirsty Tate must race against time to retrieve Trixie's magic before the whole holiday is ruined by fear and chaos.
