The NEW YORK TIMES bestselling Middle Grade debut from Dhonielle Clayton.

'The Marvellers deserves the highest compliment I can give a book: I want to live in this world' - Rick Riordan, author of the Percy Jackson series

Eleven-year-old Ella Durand is the first Conjuror to attend the Arcanum Training Institute, a magic school in the clouds for Marvellers from around the world. Ella discovers that being the first isn't easy but she finds friendship in fellow misfits Brigit, a girl who hates magic, and Jason, a boy with a fondness for magical creatures and support from her Elixirs teacher, Masterji Thakur.

Then the notorious Ace of Anarchy escapes prison, supposedly with a Conjuror's aid, and Ella finds herself as the prime suspect. Worse, Masterji Thakur mysteriously disappears while away on a research trip. With the help of her friends and her own growing powers, Ella must find a way to clear her family's name and track down her mentor before it's too late.

The perfect next read for fans of AMARI AND THE NIGHT BROTHERS and SKANDAR AND THE UNICORN THIEF!
