The Goodness Potion and its Side-Effects (Hardcover) (ISBN-13: 9781739534905)

There's good and bad in everyone. Except Tom.

Tom used to think his life was pretty ordinary. Just another orphan, sleeping in the cellar of his uncle's pub with plenty of mice to chase. But then things started to change, both in the land of Boden-Rine and in young Tom's heart, after a stranger from a far-off land spun him a story of deadly adventure and world-ending peril. Oh, and something about a baby fourteen years ago drinking a potion with the power to make a person either wholly good or bad. That baby grew up to be... Tom.

Now, Tom's life and the fate of the world depend on the answer to a single question: Which one is he: good or bad?
