A highly entertaining Young Adult spy thriller with several interesting twists and turns. For young readers who are too old to read children books, but too young to read more action-loaded novels, this series is the perfect choice. I have especially positive memories about the well-developed antagonist in this story. A lot of political stuff was included without ever sounding boring or overloaded to the ten-year-old me who read (and reread) this book a long time ago.
