royo's books are for the most part wordless, and work well as such, secrets was a wonderful book because the explanations of the pieces were brilliantly terse, poetic and intriguing, but his work in general doesn't need them, this is an exceptions, it's a great sketch book, by which i mean that if someone handed you it after having applied the markings themselves it wold be great, but as a mass produced book it just doesn't work quite as well, it needs words of explanation and the thoughts that went into the pieces, perhaps it would work without words if it actually showed the development of the pieces from start to finish rather than just a sketch of it, a snap shot of development....still they are some fantastic drawings in here, Luis Royo is a brilliant artist.
