The Secrets and Peculiar Adventures of Jillian Dangerous was an awesome book because of all the twists and turns. I really liked the relationship between the roomates because they would help each other out and support each other. I also liked how the setting was at a boarding school because it reminded me of Harry Potter. One other thing that was interesting about this book was that when the girls traveled back in time to 1965, Jillian and her mother were friends. There was nothing that I did not like about this book. I hope the story will continue and become part of a series because I definitely want to read more. I would rate this book 5 of 5 stars, and I would recommend this book to ages 10 and up.
