"Pluto is peeved. And who can blame him? He was proud to be a member of the solar system's nine planets, until Poof!, he was kicked out -- and no one told him why. Now Pluto is on a mission to find out why he was expelled. While traveling through the science museum, he meets a friendly dinosaur, some wild-and-crazy germs, and a few real planets. It turns out that he's not the only one whose life has been turned upside down by scientists. They've done it to everyone, in their own mission to discover the truth. Pluto is peeved? is a lively exploration of the scientific method, as seen through the eyes of one no-longer-angry ex-planet" --P. [4] of cover.
