"Listeners will enjoy this fresh take on a new fantastical world in which kids play an active role in determining the future of society." -AudioFile on The Marvellers

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, like brewing Indian spice elixirs and bartering with pesky Irish pixies.

Despite her excitement, Ella discovers that being the first isn’t easy—some Marvellers mistrust her magic, which they deem “bad and unnatural.” But eventually, she finds friends in elixirs teacher, Masterji Thakur, and fellow misfits Brigit, a girl who hates magic, and Jason, a boy with a fondness for magical creatures.

When a dangerous criminal known as the Ace of Anarchy escapes prison, supposedly with a Conjuror’s aid, tensions grow in the Marvellian world and 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.

"A marvelous gift of a novel! With fantastical twists at every turn, Clayton has created a world that readers won't want to leave.” —Angie Thomas, #1 New York Times-bestselling author of The Hate U Give and Concrete Rose
