(from back cover) Sally and Lucinda and their new friend, Phoebe, are out to make some magic. Phoebe's grandmother, Maya, has been feeling depressed lately, and Lucinda has just the solution. They'll make her a magic youth potion! But after the girls secretly give the special drink to Maya, something goes terribly wrong. Why is Maya acting so strange? Could the potion actually be dangerous? Phoebe just wants her grandmother back to normal again and she needs Lucinda's help. But Lucinda is only a junior witch-she doesn't always have all the answers. And this time, she may be in over her head.
