The design of a novels cover.

The design of the the novels cover is a crucial part of selling a book.  For example the way some people choose to read different novels is by the front cover, and this means that if the novels front cover isn't appealing to the eyes of a reader, than it will not be sold or borrowed, thus not being read. I personally do not like the design of the cover for the novel 'Percy Jackson and the lightning thief', I believe that it is too crowded and messy, that the designer had  too many good ideas to fit onto a small book. Even one of my classmates Cody Howley did not like the design of the front cover. His first thoughts were: oh, you like to read books about fighting monsters and dragons. (He did not believe in; do not judge a book by its cover)
But maybe he would read it if it had a better design of the cover and realise the Godlyness of the book.

I think that the ideal cover for a novel has to be simple, but detailed enough to be able to grab someones attention. But the cover 'Percy Jackson and the lightning thief' had way too much detail for my liking. But the book I i read, has three different types of front cover. The particular one I read had too many things on it. Here are the pics of the three novels: (The one I read is in the middle)
