Ruby Miles went back in time from 2022 to 1878 to meet Kate Kelly (Ned Kelly’s sister). They looked the same and they were both adventurous and fearless. They worked together to nearly save Ned Kelly and confused the police. I enjoyed the book because of the time horses (where they went to moonlight track and heard galloping and the horses were travelling in time). I would recommend this book to people 9+ and who are interested in historical fiction.
