No Bones About It! — Nancy Krulik

Katie is an ordinary third-grader -- except for one very extraordinary problem! She accidentally wished on a shooting star to be anyone but herself. But what Katie soon learns is that wishes really do come true -- and in the strangest ways . . .

Katie's class is on a field trip to the Natural History Museum. But this field trip is not a lot of fun -- the kids are really acting up, and their tour guide is a big meanie! But when Katie turns into their tour guide, she causes a big disaster of her own. Will Katie be able to get the field trip back on the right track?
