Bought a book on sketching

I recently bought a 'learn to sketch' book referred by an artist whose drawings I like, thinking that I would like the other artist's sketches as well. Boy was I wrong. I don't like this other guy's work at all! This was an Internet buy, so I wasn't able to check it out in the same way one can look thru books in Amazon- even though it was a 3rd party buy through Amazon. Just sharing my disappointment.
