My favourite characters are Lily and her mechanical fox, Malkin. I like Lily as she always wants an adventure and she is just like me. I also like her pet mechanical, Malkin, as he is always getting in the way and bothering people. I recommend this book for someone who always loves mysteries and adventures, like me. I have loved reading the book, Cogheart, and finding out the mysteries of Lily’s father. This is one of the best books I have read in my whole life.
