Dark Times: The wildly improbable illustrated time-travelling adventure in diary format, perfect for children ages 12+ (Emily the Strange)

Emily is not your average 13-year-old girl. She wears the same black dress everyday. She loves maths and science. Her best friends are four black cats and she's into old rock and punk music. In this book Emily travels back in time to the 18th century to learn the truth behind a class assignment. Naturally, mayhem ensues.
