This epic fantasy novel for middle grade readers has fun potion-making, faithful animal friends, and fantastical adventures. Mendel, an eccentric boy with an autistic nature, and the master alchemist Sir Duffy set out on a series of quests with their many weird and endearing creature companions—like Esther the snake-ish gusselsnuff, and Gooder the fat, lazy, carnivorous horse. These determined travelers must venture across the continent of Terra Copia, an exotic land where the plants and animals in one forest are completely different from the next. It is up to them to safeguard secrets and dangerous artifacts from many enemies—such as agents from the Academy of Advanced Disciplines, venomous pixies, and a mysterious pale stranger. If they fail, a terrifying curse will return to their land. The Harry Potter audience will love the world of The Alchemist’s Theorem, and all of its magical alchemy, fantastical beasts, and epic adventure. "A rather dashing adventure from a new voice in the Middle Grade Fantasy arena that appears to have staying power.”—Insatiable Readers "Chiavetta avoids showing autism as either an entirely crippling illness or a special gift in and of itself. Mendel has autism and he has to learn ways of coping with the world... It becomes one aspect of who he is, not the sole defining quality of an inquisitive and inventive young man.” —Fangirlnation
