There is a girl called Lilly and everyone thinks her dad has died. But her family member Dr.Silverfish/Uncle wants this device called Cogheart. It is this mechanical heart that can keep you alive forever (I wouldn’t like that because your skin would go extremely wrinkly after 200 years) because he is really poorly. And so he had got a couple of evil people to try and find the Cogheart, but no one knows it is inside of Lilly’s body. She made a couple of friends 1st Robert his dad had died during this book. Also a fox the mechanical called Malkin who delivered a special note to Lilly and finally Anna who flew the airship all the way to London for Lilly, Robert and Malkin.
I would recommend it to people who like SHOCK, DANGER and DARING!!!!
I rate it four out of five
Because it took a long time to get into the story for me but other than that great!!!
Let me know what you think of my review in the comments below…
