This book starts as Alex Rider (a teenage spy) not wanting to join MI6 (a secret intelligence service) again after his Snakehead experience (in the 7th novel) and he just wants to lead a normal life. When he goes to Scotland with his friend to spend the New Year at a party in a castle overlooking Loch Akraig and Alex wanders into a casino in the castle and gets involved, things start to get serious.- Desmond McCain (host of the party and says that all the money raised in the party will go to a charity, First Aid) is one of the other players as well as a man who Alex thinks looks like an accountant. But when Alex wins a whole load of events happens in quick succession to make him get involved with MI6 again and has to carry out a mission whilst on a Geography field trip.
This book was relatively easy to read and there weren't that many words in the story that I didn't know the meaning of. The main characters are described very well in their appearance especially Desmand McCain. The settings were very realistic and described very successfully especially around Loch Akraig and all the senses were used well. The main themes in this book are adventure and escape because Alex is very adventurous in the missions he takes on however there are escape scenes once he has undertaken the the missions to get out successfully.
Overall I would give this book 9/10 because although the book is very good some of the scenes start to be predictable.
