It all started with a book. The most boring book in the world. So boring that nobody would ever read it - which makes it the perfect place to hide a terrible secret.

Teenagers Luke and Tommy stumble across this lost book, worth millions and somehow mysteriously connected to Leonardo da Vinci.

But they are not the only ones seeking the book. Soon they are fighting for their lives.

Now the book has emerged from its hiding place the world may never be the same.
