Author Benjamin Wiker leads the reader on a delightful and absorbing journey through the ages, on the trail of the elements of the Periodic Table as we know them today. He introduces the young reader to people like Von Helmont, Boyle, Stahl, Priestly, Cavendish, Lavoisier, and their successors, all incredibly diverse in personality and approach.  Their questions and experiments, and the unraveling of their misunderstandings form the basis of Dr. Wiker's witty, but solidly instructive presentation.  It is suitable to middle school age, with the later chapters designed for ages 12-13 and up, and a final chapter somewhat more advanced.  Young and old alike are invited to explore the mystery, tasting the perils—and pleasures—of an ongoing adventure.
