The book involves an elaborate plot surrounding famous objects. The author has done a great deal of research, for he has a historical fact attached to almost everything REAL mentioned in the book. You may come across facts in this book that you have heard of before. For example, in Bones or in The National Treasure. But this book definitely interprets them in a unique way. Awesome employment of imagination by the author.
The author has used short chapters, each ending with a so-called gripping moment. Nice use of italicized sentences to show what the characters were thinking.
The book involves a really good plot-twist – sort of like the one involving Jim Gordon in The Dark Knight or Barty Crouch Jr in The Goblet of Fire. Pages 320–420 of the book were the best – people running around, clues coming alive in every direction, and a race to save the nation. But the final 30 pages were a COMPLETE let down. They were too dragged out and I kept getting lost.
PS: I'll still recommend this book to my friends, but I'll advice them to keep their expectations short.
