Photographers Susan Middleton and David Liittschwager are in a race against the clock to capture powerful portraits of America's most threatened creatures. In their adventures they encounter a camera-shy blackfooted ferret, capture the beauty of golden trout, help release a pair of red wolves back to the wild, and watch from a front-row seat as a bald eagle chick is returned to its cliffside nest. Their every picture tells a story and makes a plea: don't say goodbye to America's natural treasures.
