Just as a pebble is part of a mountain, just as a wave is part of the sea, so, too, is every one of us part of something bigger. With bright collage illustrations and a simple, lyrical text, acclaimed author-illustrator Toni Yuly invites readers to celebrate our relationship to the natural world.

Sent outside by their mother, two rambunctious children explore their own garden, deserts, mountains, oceans, and jungles and encounter many species of animals that are endangered or nearly extinct. Includes an index of the animals and each one's level of vulnerability to extinction.

It is spring in the park, and after the rain falls babies play and giggle, while birds and animals sing and sleep.
