As if that prospect weren't scary enough, thirteen is when a Beaumont's savvy strikes -- and with one brother who causes hurricanes and another who creates electricity, it promises to be outrageous ... and positively thrilling. But Just before her big day, Poppa is in a terrible accident. Suddenly, Mibs's dreams of X-ray vision disappear like a flash of her brother's lightning: All she wants now is a savvy that will save Poppa. In fact, Mibs is so sure she'll get that powerful savvy that she sneaks a ride to the hospital on a rickety bus, with her siblings and the preacher's kids in tow. But when the bus starts heading in the wrong direction only one thing is certain: After this extraordinary adventure, not a soul on board will ever be the same.
