Now in paperback, here's another rollicking collaboration of Robert Munsch and Michael Martchenko. Young daredevil Lauretta puts her brand-new wheelchair to the ultimate test--and saves her brother! Lauretta's mother takes her to buy a new wheelchair, but Lauretta isn't satisfied with a regular five-speed or ten-speed model. No, she insists on the 92-speed, black, silver, and red dirt-bike wheelchair. When she gets a speeding ticket during a one-day tryout, her parents insist that the chair be returned to the store . . . until Lauretta's older brother has an accident and only one person can whisk him to the hospital on time--Lauretta, in her amazing wheelchair!
