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 new and neanderthal alike.
