I saw this review yesterday and was reminded how much I love this story!
This is the charming prelude to a new series of novel. A good narrative, enjoyable protagonists and friends and family members, and best of all the author is showing us San Francisco in the period right after World War II, and the research rings trues in details of clothing and speech. I was slightly younger than the protagonists (11 years at the time), so I remember it well. The two first entries are novellas, while the next stories are full novels.
