This is the best of the first four Sarah, Plain and Tall books. Patricia MacLachlan carefully rations out her writing for the limited space given to this story and tells it beautifully, with even more engaging emotion than is to be found in the first three books. Few authors are more skillful than Patricia MacLachlan at penning a sensitive and impactful story in so few words, and More Perfect than the Moon is an exquisite example of just how well Ms. MacLachlan can bring an idea to vivid life in only a few dozen pages.
After the third book in this series, Caleb's Story, Caleb passed on the responsibility of keeping the family journal to the new youngest child, Cassie. Cassie is the first child born to the marriage union of Jacob and Sarah, Caleb and his older sister, Anna, having been born to their own Mama who died years before Sarah joined the family in the Newbery Medal-winning book Sarah, Plain and Tall. Cassie has a very different style of writing than her two siblings who previously kept the journal; she loves to make up stories and fill her notebook with ideas and imaginings of what might be and what she hopes will happen. In this way, she hopes that a few of her wishes may even have a chance of coming true.
When Sarah becomes sick, Cassie gravely worries about her mother's health, but it turns out that it's not a serious health issue after all. Changes will be coming to Cassie's home, just as changes came for Anna and Caleb before, and the family will have to change and grow to keep up with what's going on around them. Cassie isn't sure that she likes the idea of things permanently changing in the comfortable home that she already knows, but perhaps she just doesn't yet realize that though her yearning for a perfect gift may not ever be completely fulfilled, a more than adequate substitute for perfection may illuminate new possibilities in her life that she'd never even known were there.
Patricia MacLachlan has done a wonderful job with this book. The story is sweetly told and grand in its emotional simplicity, never straying from the path of winsome plainness set up in the previous three books. I couldn't have realistically expected more from this book than I got, and I would recommend More Perfect than the Moon with greater enthusiasm than I had for its predecessors. All told, there's a good chance that I would give this book the full three stars.
