Sintesi dell'editore

A puzzle left behind by Sifu Faiza's grandfather has everyone stumped. A circle divided into wedges shows part of the formula for an ancient medicine. But some of the wedges are blank, and no one knows how or why the original formula disappeared! Joy, Adam, Amy, and Sam will have to use clues - and fractions - to discover the truth about...the ancient formula.
