A poetic personification of the spring season, Sister Spring is revealed to be the force behind beautiful sunrises, blooming trees, sudden showers, and other springtime wonders.

After Sister Spring awakes "with the first daffodil on the very last breath of frost," she colors the sunrise with a kiss, provides thunder for the hills, and invites the reader to gambol in the meadow and "dream the seeds of the morrow." A companion to Mother Winter, this poetic celebration of springtime revels in the life-affirming renewal of the season.
