Along with her cat, Mistress Puff, Ada gets into all sorts of trouble. According to her mother, Ada is a bit too wild, so she encourages Ada to study math.At first, Ada thinks: Bleh! Who can get excited about a subject without pictures? But she soon falls in love with math inspired by women like her governess (Miss Stamp), her mentor (Mary Somerville), and even her mother (Lady Anabella Byron, the Princess of Parallelograms).When Ada is older, she meets an eccentric man who turns out to be the renowned British inventor, Charles Babbage. At his house, she encounters a mysterious machine which unlocks a future full of possibilities. Together with this machine and her new friendship, Ada will become the inventor of the first computer programming language in history.
