Charles Babbage and The Countess

After finishing the book, very strong impression remained from last 100 pages. The book keeps reader interested from early beginning to the very end. It goes chronologically, and in the beginning the chapters about Babbage alternates with chapters about Ada until they meet. Since then, the book describes their intervening life stories. The author describes Ada's mother in pretty negative light, which sometimes pushes reader to think twice about her character. In the middle, it's not quite sure if her characteristics are really as bad as the author tries to paint them. Book provides a lot of interesting material for discussion, so I imagine I would thoroughly enjoy discussing this book with someone who read it or who knows about the material from other sources. Personally, I highly recommend this book to everyone who is interested in topic of Charles Babbage, his Difference and Analytical engines, and lastly, but most importantly, in Ada's Byron Lovelace life.
