Some kids are too smart for their own good...and maybe for everybody elses good. The overly ambitious little girl from Oh No! is back for more. But this time she doesnt have a humongous problem; she has an EPIC crisis on her hands: a mere A on her history test! Theres only one solution: travel back in time to 33000 B.C. to make her wrong answer right! Mac Barnett and Dan Santats 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.
