Cogheart is set in 1896 Victorian London and it's about Lily Grantham who is 13 years old. Lily's life is turned upside-down after finding out her father has been in an airship accident. There's a lot of action and adventure in this book, and you'll never know what's going to happen next but you'll be in suspense to find out. It has great mystery and lots of imagination - and I also loved the idea of a mechanical fox!
