Beautiful color photos illustrate this scientific success story of bringing back this species of monkeys from approaching extinction to a viable population.  Crossing fifty years of concern and study and attempts and failures and more attempts, the book teaches about the needs of golden lion tamarins, about the growth of environmental science, about the interrelationship between animals and their environments, and about how humans can impact that relationship, both for ill and for good.  It honestly shares the complexities of trying to release animals born in captivity into the wild. It’s a book to inspire.
