Fourteen year old Alex Van Helsing is related to the famous Van Helsing. He possesses the power to "feel" a vampires presence. This proves useful for vampire hunting and for protection from vampire hunters. This is a fast action novel with lots of action, vampire "deaths" and just a smidge of teen romance, a hint more than a smidge, really. It's the perfect boy book.
I really loved the first book with it's background history on the classic horror authors. This sequel had a great storyline but left Alex to deal with a major character without the help of the Polidorium. It felt like the junior "James Bond" was forgotten by his "country". I'm sure the younger set loved that Alex and his friends did just fine on their own.
