Judging a book by its cover

My initial thought when seeing “Natural selection” was that it is going to be a very suspenseful book with a lot of plot along with a mysterious person or animal that will make the story exciting to read. The description on the back made me interested in the book by describing a creature in a vague way that made me want to learn more. I decided this was the book I wanted to read because it seems interesting with a good story. I expect that this book will be a page turner because it will make you wonder when the monster will appear next and how they will beat it.
