While Laura Ingalls grows up in a little house on the western prairie, Almanzo Wilder is living on a big farm in New York State. Almanzo and his brother and sisters help with the summer planting and fall harvest. In winter there is wood to be chopped and great slabs of ice to be cut from the river and stored. Almanzo wishes for just one thing-his very own horse-but he must prove that he is ready for such a big responsibility.

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.
