New York Times-bestselling author Dhonielle Clayton makes her middle-grade debut with a fantasy adventure set in a global magic school in the sky, perfect for fans of Rick Riordan, Soman Chainani and Melissa de la Cruz.

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.

But Ella discovers that being the first isn't easy, and not all of the Marvellers are welcoming. Still, she connects with fellow misfits Brigit, a girl who hates magic, and Jason, who is never found without a magical creature or two. Just as Ella begins to find her way at the A.T.I., a notorious criminal escapes from prison, supposedly with Conjurors' help. Worse, her favorite teacher Masterji Thakur never returns from a research trip, and only Ella seems concerned about his disappearance.

As tensions grow in the Marvellian world, Ella finds herself the target of vicious rumors and growing suspicions. With the help of her new friends, Ella must find a way to clear her family's name and track down her beloved mentor Masterji Thakur . . . before she loses her place at the A.T.I. forever.
