I like this book because of the excitement. Robbie was always going up trails, sometimes turning back to the main trail until she found the correct answer. I couldn’t stop reading the book after the first page. The entire book was realistic. The characters were very real. The fights always sounded like what fights are. The characters appeared to be like normal people. Robbie was like a real detective, but she didn’t go past the boundaries of being a teen. This book is good for anyone 12+. I recommend it to anyone who loves mystery mixed with adventure.
