I read this book without having read any of the Blossom Street books (beyond the second one). Enough information was provided on each of the Blossom Street "regulars" that I now don't feel a need to go back and catch up. Based on the quality of this story, I feel this saved me a great deal of time.
Bethanne, the woman who started a successful line of party stores after her husband cheated on her, is advised by her 22 year old daughter that Grant (the ex) wants a second shot at their marriage. Six years have passed and Bethanne isn't certain what she wants to do. A chance lunch with her former mother-in-law reveals an opportunity for a long road trip (WA state to FL state) and time to examine all the new questions and relationships she finds along the way.
Granddaughter Annie horns in on the trip, taking every opportunity to act in a very childish manner and attempts to manipulate her mother into giving Grant another chance. It's clear Annie should not be sticking her nose into anyone else's business. Bethanne allows herself to forget she is a capable and intelligent businesswoman, focusing instead on illogical and fluttery ideas.
Really, I was sorely disappointed in the way all of the characters in the book, with exception of Andrew (Bethanne and Grant's grown son) behaved. He was the best of the group.
Loved, loved, loved this book. This road trip was both funny and endearing.
