The Penderwicks at Last by Jeanne Birdsall

Lydia, youngest of the Penderwick siblings, is eleven years old, and terribly excited: for a special family event, the whole Penderwick family will be revisiting Arundel, a place that Lydia finds as magical and mystical as Camelot or Narnia. All her life, she's heard the family stories about the summer vacation where her four older sisters met Jeffrey and his awful mother, Mrs. Tifton. Now, she will actually see Arundel with her own eyes. What adventures await?

This is the last Penderwick book, which is bittersweet indeed -- but the story itself is as light and airy as the first, full of delightful new characters to love as well as appearances by many old favorites. It's a fitting end to the series, wrapping it all up in the same place it started. I was satisfied with the way the relationships among the older characters resolved, though I imagine that some readers will quibble. If you have read and loved the other books in this series, you will not want to miss this one.
