This companion novel to the Betsy-Tacy series first came out in the 1950s, and it is not as well-known as the other books. I never read it as a child, but I enjoyed reading it as an adult, and the story will particularly appeal to tomboyish girls and those who love horses. It's a cute, short chapter book with lots of great dialogue and real life humor, and even though the ending seems like wish fulfillment, I enjoyed the book overall.
Winona first appeared in the fourth book, and is a school friend of Betsy, Tacy, and Tib. In this story, she is preparing for her birthday party, and even though her mother has invited a set group of children, she extends invitations to lots of friends in town. When I was a child, the vicarious embarrassment of this situation would have overwhelmed me, but I found it cute and amusing as an adult, especially considering the realistic contrast between Winona's free and easy friendship and her mother's selection of Suitable Children based on race, class, and whose mothers she was friends with.
Winona and her mother both learn from the experience, and I appreciated the subplot related to the Syrian immigrant children Winona invited. Maud Hart Lovelace was ahead of her time regarding the local Syrian population, and in this companion novel, she picks up this aspect of her characters' world again from past books. Winona invites to her party some Syrian children she is friends with, and they are portrayed in a positive light, helping the mother get past her own paradigm about who her daughter should associate with.
This is a short, simple story, and it conveys realistic family and community dynamics in a way that can appeal to both children and adults. As a kid, I would have been most invested in the pony storyline, but there is far more thematic depth here than seemed apparent based on the premise, and I found it very interesting. I'm glad I had the chance to read it.
