From the author of The Castle of 1,000 Doors comes the first book of The School Beneath the City trilogy, the story of three magical students destined to save the world.

For the first time in the history of Wunder's School for Brewing Excellence, three students are tied for valedictorian. To break the tie, Dr. Wunder issues a challenge: the student who makes the best final potion will earn the coveted title of Potionmaster.

But as the students compete, an ancient evil is rising from a long overdue slumber. It's a magic even Dr. Wunder can't stop. And the students pitted against each other might become the world's only hope for survival.
