" Scab McNally, a fourth grader, loves coming up with inventions including sister-repellent spray a.k.a. Isabelle's Smell. Can he sell enough of this sister-repellent to buy a dog, something he has wanted forever? Funny series. Good for kids who like Stink, Roscoe Riley, Diary of a Wimpy Kid etc. "
