Definitely, like many others, it was the unexpected cancellation of the TV show which created the appeal to buy this item. Despite the fact that the TV series was popular here in Turkey too, I was not able to find a Turkish translation, nor the original of the book in national bookstores so I looked it up here on Amazon. It arrived in 10 working days, which is reasonable.
The TV series, as I should have guessed has too little in common with the book. The TV series carries the story to USA and makes it a crime series, involving FBI and CIA, while the book dives into astrophysics and philosophy and keeps it within European boundaries with slight touches of Canada (tribute to the author's mainland). It only has one common character with the TV series and another with a similar fate to a character in TV series, other than that the book was merely an inspiration for the producers.
The plot is interesting though. Once you realize it has nothing to with criminal agenda, you accept it and read it with strong curiosity. The book itself feeds you that curiosity and lures you into its depths. There are some parts that it literally fast-forwards, not to bore the reader I guess and you don't miss the details that it skips. Towards the end it really speeds up, give you the adrenalin that a book can and makes you read faster and faster and it unwinds the secrets it had hidden from you all from the beginning.
To me the conclusion, the explanations and the final twists of those explanations were not as satisfactory as I thought it would be. I do not want to give any spoilers but when I closed up the book I asked myself; was it worth it? Well, yes, of course, rather than not knowing what lies behind that curious TV series reading the book gave me something. But not quite the thrill and amazement that I expected it to give to me.
So my rating is 3/5. The book is not as good as a 4, but definitely far better than a 2. Just don't expect too much.
