I thought it did a fair job with the suspense and action, but it could have been better with the storyline. I like when stories get to the point, but this one was a little too hasty with the first three chapters. First, they would talk about the agency and the main characters' connections to it, then they would dive directly into the mission. I know the book was meant to let readers guess what was happening in the book, but I wasn't able to follow it all. I could understand what was going on after chapter five, but I couldn't understand the entire mystery. ( )

I really liked the idea of the book- An orphan raised by a secret agency, not knowing if she can trust anyone, even her 'friends'. It did remind me a bit of an old T.V. show called 'The Pretender' and seemed to be a cross between that and Spy Kids. Ultimately, this book did not win me over.

My low rating of it is due to the rushed feeling I had while reading it. What was possibly intended to convey urgency and suspense had a different effect on me. I found that I wanted more information on the characters themselves and some background. I understand that the lack of facts about the characters is part of the story, but without a bit more foundation for the story I never became invested in who they were or what they were doing. Instead I felt like I was thrown into the action too quickly, with not enough time to look around and understand/appreciate what was happening before I was pushed into the next scene.

I may at some point try the next volume but for now I won't be looking for book #2. ( )

I love this book! It is full of mystery and suspence. I know that the title "Undercover girl" sounds cheesy and corny but it is an excelent book. I recommend this book to anyone who loves mystery and suspence.
