When Wren was born, Grandpa put a wren box just outside the window of her tiny room. Each spring, Wren and Grandpa watched the birds bringing sticks and grasses to the box and listened when the babies squealed for their dinner. Their new home has an extra bedroom, but the only birds she can see are pigeons. Lots of pigeons. But when Wren and her grandpa discover a phoebe nest in the rafters above their porch, they get a front-row seat to the miracle of new life.
