Book Description: Gemini Jack is back in his shop at the Middle Valley Mall, and once again heâ€™s hoping twins Tod and Tessa can help him with problems on his home planet. But Tod and Tessa have problems of their own. The Gneiss twins, once so evil they scared their own mother, are now sickeningly nice. Itâ€™s as if the entire balance of the universe has gone kablooey! Then Tod and Tessa use one of Jackâ€™s gadgets to help the great rock drummer, Nigel Throbber, escape from his fame temporarilyâ€“only to learn the effects are permanent! Now they need to give Nigel back his celebrity, save Jackâ€™s planet, and convince Nancy Gneiss that she doesnâ€™t really have a crush on Tod. Which makes restoring the balance of the universe look like a breeze. . . .
