Some kids are too smart for their own good…and maybe for everybody else's good. The overly ambitious little girl from Oh No! is back for more. But this time, she doesn't have a humongous problem, she has an EPIC crisis on her hands: a mere A on her history test! There's only one solution: travel back in time to 33,000 B.C. to make her wrong answer right! Mac Barnett and Dan Santat's laugh-out-loud sequel to the critically acclaimed Oh No! will be sure to tickle a prehistoric funny bone for fans of humor, comics, and outrageous adventure.
