I started the series because when I was younger I found the spy thing to be very intriguing. Sadly I realized that I am a little too old for the books. Don't get me wrong, they are funny, unique, clever and overall a really nice read but the problem is that they are more on the young side of the young-adult category. I am very glad that I didn't give up on them (I just can't leave series unfinished..huge problem and time-consuming). The books keep getting better and better to the point that I ended up giving them 5 stars. I won't nevertheless, recommend them to everybody. They are definitely for a younger group and for those with silly childhood dreams of becoming a spy.
