'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

'A richly imagined world with characters I wish I could meet and magic that filled my dreams for days afterwards. I didn't want it to end - when is the next one out!?' - A. F. Steadman, author of Skandar and the Unicorn Thief

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.
