Book or treasure hunt?

It aya two ways to read this book.
Read simply. Then there is a simple writing and sometimes simplistic or minimalist and therefore accessible including young readers. It is written in the present, as a script. No complicated vocabulary. No convoluted sentences ...
The scenario is simple, linear with little stories hidden in the large.
Some Dan Brown found there for the inclusion of existing historical places in history; some stargate for extraterrestrial creators and posing as gods, and many Hunger Games in much less well written.

You can also read this book trying to solve the riddle. And there, it is not at all the same reading. It becomes a different experience which combines reading, reading augmented with links to Internet pages, the need to bring paper, pencil, calculator ... and everything necessary to solve the problems .

In the first approach, we can reach the end in 2 or 3 days. For puzzles, it depends on the sagacity of the reader, and it is assumed that if the sum put into games is so high ($ 500,000) is that this is not an arrow word of the Sunday newspaper!
