In the zoo there are all kinds of animal families. But Tango's family is not like any of the others.

This illustrated children's book fictionalizes the true story of two male penguins who became partners and raised a penguin chick in the Central Park Zoo.

At the penguin house at the Central Park Zoo, two penguins named Roy and Silo were a little bit different from the others. But their desire for a family was the same. And with the help of a kindly zookeeper, Roy and Silo got the chance to welcome a baby penguin of their very own!
