The Five Lost Aunts of Harriet Bean by Alexander McCall Smith

Harriet Bean has always known her father was a little absent-minded. Okay, a lot absent-minded. But that seems to just go with the territory when your father is an inventor, doesn't it? And over the years, Harriet Bean has found ways to deal with her father's cloudy thoughts.

But despite all of her experience, Harriet Bean still finds it hard to believe that her father can have forgotten to tell her about her aunts - her father's five sisters!

It takes some coaxing, several days, and an entire plate of scones, but Harriet eventually learns about Veronica, who was incredibly strong; Japonica and Thessalonika, the twins who could read minds; Majolica, who was alway very bossy; and Harmonica, who sang as sweetly as a nightingale and was a ventriloquist to boot.

Now as you can probably imagine, such exciting descriptions made Harriet Bean determined to meet her aunts (finally!). There's just one problem - her father doesn't know where any of them are! He only has the address for Veronica, and that's 10 years old.

But Harriet Bean isn't going to let that stop her - well, would you?
