"Eleven-year-old Ella Durand is the first Conjuror to attend the Arcanum Training Institute, a magic school in the clouds where Marvellers from around the world practice their cultural arts. Despite her excitement, Ella discovers that being the first isn't easy--some Marvellers mistrust her magic. Eventually, she finds friends in elixirs teacher, Masterji Thakur, and fellow misfits Brigit and Jason. When a dangerous criminal escapes prison, supposedly with a Conjuror's aid, Ella becomes the target of suspicion. 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"--Provided by publisher.
