This lyrical adventure follows the bluefin tuna, puffin, sea turtle, and Atlantic salmon through their life cycle. Each of these special species has a characteristic called natal homing. They're born, leave home to eat and mate, and then return to precisely where they were born to start their own families. This is a scientific look at these animals' habits--but includes a parallel story reflecting humans' own tendency to return home. Science and nature backmatter includes additional information on the included animals as well as an author's note.
