There’s a magic school in the clouds where Marvellers gather from around the world to attend the Arcanum Training Institute and practice their cultural arts. Join 11-year-old Ella Durand, the first Conjuror to attend, and the friends she meets: the elixirs teacher Masterji Thakur, Brigit and Jason. Ella finds herself in trouble when the Ace of Anarchy, a dangerous criminal, escapes prison and some Marvellians suspect that she had something to do with it!
