I was very excited to read this book after really enjoying the original series about the twins' brother, Artemis. I was not disappointed, though it wasn't quite as great as the first book in the companion series. The humor is still very much there and the antics of the twins added an excellent layer. If you've not read about Artemis's antics, I would highly recommend it although it's definitely not necessary before starting this series. I would have enjoyed some more time spent between the villains (yes, there is more than one) and the twins as well as maybe some more interaction between the twins and their brother, if only to have the torch passed on. Overall though, this is a series I'll be following and one I would definitely recommend.
