I have just come home from a lovely celebration for a friend's baby, Ada Grace. For the last week I have been agonising about what gift to give her. I always give this family books, so I felt quite sure they would expect me to arrive with books, but what to take? I had given Ada's older sister picture book bible stories for her baptism, but felt I had chosen the best of these then. So finally I decided to give Ada some books about exemplary Adas. Well as it turned out I had a lot to choose from, all of which she would grow into at some stage. In the end I bought a current favourite, Ada Twist, Scientist and one of the wonderful biographies on Ada Lovelace, Ada's Ideas, but it could have just as easily been any of these below. The one at the top right is book one of a new series about Ada Lace, an eight-year-old girl with a knack for science, maths, and solving mysteries with technology. It will be out in August and I will buy it for the library.
