The Secret Journal of Beatrice Hassi Barahal is a short story with illustrations by Julie Dillon. Set in the world of Cold Magic, it is written from the point of view of Bee rather than Cat (the narrator of the Spiritwalker Trilogy). It spans the three volumes of the Spiritwalker Trilogy and then goes beyond them as a coda or epilogue to the trilogy (answering one of the unanswered questions from the end of the third book).
