We are at the library roaming through the stacks or browsing the new releases in the local bookstore and we come across a book with an interesting title or cover and we pick it up. Opening the book to the first page, we read the opening paragraph and decide whether we want to read it or not.
As writers, we need to consider our books from a marketing standpoint. What are we selling? Why should the consumer care?
When someone reads our first paragraph, what are we telling them? What have we promised? What hints have we given them? Are we being honest with them? Is what we are promising going to continue throughout the book?
