Could anything be more perfect than a prairie wedding? Cassie doesn't think so, for a wedding brings:

Two lovebirds together,
Aunts from faraway Maine,
A long white dress with a wedding veil,
Zinnias,
Satin ribbons,
Dancing under a clear blue sky,
And a world that smells of roses.

And as the Witting family comes together for this most special day, Cassie sees that life brings:

The change of seasons,
Brother Jack on Grandfather's lap,
A brand-new car,
Joy,
Sorrow, 
And a special dance only Grandfather does.

SARAH, PLAIN AND TALL began the Witting family's saga on the prairie. Now the story completes its circle with GRANDFATHER'S DANCE. Patricia MacLachlan's poetic celebration about the enduring spirit of family.
