The third in the Dominic Grey series is another hit, with some great background on Viktor which was great. The good thing is that you can read each book as a standalone. The other two books are reviewed on my blog, The Summoner and The Egyptian.
Another dark novel, with plenty of travel between San Francisco, Paris, New York, London and Sicily.
There are no grammatical or spelling mistakes.
There is plenty of background on the subject and the author, Layton Green has done plenty of research on his subject and on the places visited. This book is almost is very hard to put down, you might find your real life gets in the way and could even be ignored.
If you liked Dan Brown´s books, well this is better.
