The author of this book tried to sue Ubisoft for "copyright issues," since his book was sort of similar to Ubisoft's "Assassin's Creed". The book wasn't popular at all (and was called "abysmal" by critics) because of so many spelling and grammatical errors, and also the idea just wasn't even remotely... I don't even know. At least Ubisoft came up with an idea that sounds like it's possible.
