"Meet George, The 3rd lord of Devonshire and the unluckiest boy in London. Why is George the unluckiest boy in London? First, he's an orphan. Second, unless he sells everything, he's going to lose his house. So when his family's last heirloom, a priceless map to the Star of Victory (a unique gem said to bring its owner success in any battle), is stolen by a group of criminals, George knows that there is no one less lucky -- or more alone -- than he is. That is, until Ada Byron, the future Countess of Lovelace, bursts into his life. She promises to help George recover his birthright and restore his family's good name, and is determined to find her own father along the way -- all in a flying machine she built herself. Joined by a boy with a mysterious past and a mischievous orangutan, George and Ada take off on a cross-continent journey through the skies that will change their lives, and perhaps the world, forever."--

Twelve-year-olds George, the very unlucky third Lord of Devonshire, and his neighbor, scientist Ada Byron, join forces against a nefarious group of criminals who steal the map to a priceless family heirloom.
