Bought on a whim and was accordingly wary that it would be a bit of a trashy thriller with little substance. In this case, I really lucked out. I absolutely loved this book. Written thoughtfully and with sophistication, it adds an unexpected coming of age element to the story with a hint of classic and plausible espionage that has been diluted in so many modern equivalents. This is just a really well written book and I will be looking into reading the next installment which is apparently out soon.
