Once readers meet Harriet, they, too, see the irony in this title. There's nothing simple about this character; she is A LOT. This is why it's understandable that at the very start of the novel, when her parents learn that mom has to go on bed rest for the next two months (the duration of her pregnancy and the bulk of Harriet's summer break), no one can blame them for shipping Harriet and her cat off to stay with her grandmother. This is where the fun begins.
Harriet is dealing with a lot of sadness throughout the novel: missing her parents, feeling bitter about having to leave home temporarily and about the impending arrival of the baby (who wasn't supposed to change anything!), and experiencing general kid feelings. Readers of all ages will notice that Harriet interacts with these feelings in different ways (and most are not too productive).
The "Just" part does come into play, unfortunately, in the sense that the development feels so limited. There's promise: an exciting mystery object, fun characters who reveal that they knew her dad as a kid, and a new location to explore with her cat and her grandmother's dog. However, none of these characters or leads really evolves into anything too gripping. In fact, when I got to the end of the book, I turned the page and audibly said, "What?!" thinking something was wrong with the file. I really enjoy this writer, including her most recent preceding middle grade book, so I am a bit surprised to find this one stopping short.
Though I do think young readers will enjoy this, and I will continue to devour this author's works, this one wasn't the most memorable for me.
