Earlier today I checked on my first book (Driftwood Island) on Amazon. I read the reports, and I looked at the graphs, and I clicked on all the little tabs. I found out that there were over 350 people that looked at the sample pages.
So I looked at it this way: people seem to like my cover art and my blurb (because those seemed to be good enough to interest people into wanting to try the sample pages) but not my writing. Two out of three is pretty good for my first try!
