Write On! — Nancy Krulik

Katie is an ordinary fourth-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 can't wait for her favorite author, Nellie Farrow, to come visit her class and tell them all about her new book. But when Katie starts working on a cool new website with Suzanne, she forgets to read the book! Then Katie turns into Nellie, just when she's about to give her presentation! Will Katie be able to turn things from wrong to write?
