Violet and Rose have shared their best secrets under the big oak tree in Clover Park. And they have found some very good small things there too. So when Johnson's Tree Services stomps in and posts a sign that says PUBLIC NOTICE-TREE REMOVAL, they know that they must do something to stop them.

When their first protest washes away in the rain, Violet and Rose feel discouraged. But then they realize that the sort of people who care most about small things, like birds not having nests and people not having a place to collect acorns, might also be the sort of people who notice very small protests. And that gives them a quite brilliant idea, one that just might save their tree, on behalf of all the small things--and small people--who love it.
