'Dodger: The Story of a Victorian Pickpocket' by Jim Eldridge is a very good book in the My Story series. Each book in the My Story series is written in diary format, with the author writing as though they are the main character.
In this book, a young boy runs away from home and survives in London for the next few years by pickpocketing.
A very interesting story that I recommend to anyone who enjoys reading historical fiction books.
