Famous children's author Suki Kabuki and her pet raptor, Rappy, wreak havoc during a visit to Ella Mentry School.

As she grows through the first years of her life in the Catskill Mountains of New York, a peregrine falcon called Frightful interacts with various humans, including the boy who raised her, a falconer who rescues her, and several unscrupulous poachers, as well as with many animals that are part of the area's ecological balance.

Josh and his two friends look for the person who stole a peregrine falcon from its nest.
