The cover of this book is awesome - I like how you can only see Ruby's eyes as it makes the cover look more mysterious. The green and pink add a nice splash of colour.
This book is full of exciting adventures, murderous villains, perplexing codes and difficult missions. Ruby is meant to be thirteen, and even though she's a 'genius', sometimes I thought she seemed more like an eleven year old. However I don't think this really matters as some people don't act their age, and that includes characters in books! My only problem with this book is that it was very slow-paced in places.
I read this all in one sitting. It was a fun book to read, and I liked imagining how Ruby would get out of the dramatic, near-death experiences she would get herself into. The secret codes Ruby and her friend used were so good that I couldn't decipher them - maybe it would've been good if the translation had been at the bottom of the page in small print or something.
I used to read other books by Lauren Child when I was little, such as Clarice Bean and Charlie and Lola, so it's nice that she's finally written a book for my current age group.
This book is fine for girls and boys aged 10-14, and could probably be read to a slightly younger child. I give it a rating of 4/5 - a point deducted for the occasional slow pace. Overall though, this is a fantastic book!
