Eleven-year-old Ella Durand is the first Conjuror to attend the Arcanum Training Institute, where Marvellers from all around the world come together to practice their cultural arts like brewing Indian spice elixirs, practicing Caribbean steel drum hypnosis, and bartering with fussy Irish faeries. Ella knows some people mistrust her Conjuror magic, often deemed "bad and unnatural," but she's eager to make a good impression-and, hopefully, some friends. Just as Ella begins to find her way at the A.T.I., a notorious criminal escapes from prison, supposedly with Conjurors' help.
