Harriet is a rising fourth grader who is dealing with a life changing event at the end of third grade; her mother is pregnant and has been put on bed rest. Harriet (who was named after the titular character in Fitzhugh's 1964 book) is not happy about the baby, and keeps reminding her parents that they said that nothing would change. Of course, things do. Since her mother is not able to take care of her, she is sent to spend the summer on an island off the coast. Nanu runs a bed and breakfast, and is looking forward to having Harriet "help" her. Harriet is even allowed to bring her pet cat, Matzo Ball, even though Nanu is not sure how her older, grumpy dog, Moneypenny, will react. Harriet's father takes her over on the ferry, tries to sweeten the deal with a doughnut, and promises her that there are adventures to be had, and perhaps even treasure in the Gingerbread House, which he doesn't explain. Harriet, who describes herself at the very beginning of the book as someone who occasionally lies and has other less than perfect qualities, let's everyone know of her displeasure. While Nanu is sympathetic, she is also busy, and expects Harriet to deal with her grief and get on with things. When cleaning out a shed behind the B&B, Harriet finds an old fashioned key, and hopes that this is what her father meant when he talked about a treasure. She investigates all of the locks that she can find in between helping out at the B&B, walking Moneypenny, and feeling sorry for herself during down moments. Will she be able to solve the mystery of the key?
Good Points
Harriet, who reminded me a bit of Calhoun's classic Katie John (1960) is right in line with other modern characters who are not afraid to let their opinions be known, like Pennypacker's Clementine, McDonald's Judy Moody, or Parks' Junie B. Jones. She's not mean spirited, but she does like to get her way. She does show more regret than many characters; she refuses to walk Moneypenny at one point, and feels bad that the dog needed to go out, and also that Nanu seems tired while walking the dog.
There are other interesting characters in the book, such as the proprietors of the local ice cream shop, a resident of the B&B called "the Captain" who is an ornithologist, and a mysterious next door neighbor, the almost 100 year old Mable Marble. Of course, Matzo Ball and Moneypenny figure largely in the story as well.
There are a fair number of line illustrations accompanying the text, which is always a great addition to books for elementary readers. The Dung Ho pictures are slightly reminiscent of LeUyen Pham's work in Snyder's Any Which Wall or Moore's Freckleface Strawberry. Harriet is adorable, as is Matzo Ball-- the eyes are especially expressive, and it's sweet that Harriet is wearing a pair of her father's childhood overalls.
I wouldn't be surprised if we see Harriet again, since this author's Bat and Starla Jean each have a couple of books about them. Any books about adventures during the summer, especially ones that involve mystery and treasure on an island, are bound to be popular!
