Having read the first book in this series - A Mutiny in Time - my sons were really pleased when they saw that this book was available. They also read this really quickly and, like its predecessor, it sneakily provides a whole host of historical facts in the guise of an exciting adventure.
This adventure sees the kids in Paris...and the Vikings are attacking en masse. Things really don't look good - can they save the day again? This book has a little more gory detail that the first book but my sons weren't phased. To be honest, if your kids read Horrible Histories and that sort of thing then this, hopefully, shouldn't be anything that they can't take in their stride.
If I'm brutally honest then I would say that I find the characters in the book pretty stereotyped. However, the kids didn't seem to mind this at all and they even go so far as to say that they really like the characters in the book, so who am I to argue? Once again, once you've finished the book you can go onto the Internet and play on-line which, (of course!), the boys loved and which is a real bonus of this series.
Overall, once again I'm impressed by the historical knowledge that this book imparts without the kids really realising that they're actually learning. This series seems really well thought out so far and I, and more importantly the young readers in the family, are big fans.
